A study was conducted of 90 adult male patients following a new treatment for congestive heart failure. One of the variables measured on the patients was the increase in exercise capacity (in minutes) over a 4-week treatment period. The previous treatment regime had produced an average increase of μ=2 minutes. The researchers wanted to evaluate whether the new treatment had increased the value of μ in comparison to the previous treatment. The data yielded y(bar)=2.17 and s=1.05.
(a) if the actual value of mu is 2.1 and alpha is reduced from 0.05 to 0.01, what would be the effect on the power curve?
(b) If the sample size is reduced from 90 to 50, what would be the effect on the power curve?

Answers

a. Decreasing alpha from 0.05 to 0.01 makes the significance level more stringent. You will be less likely to reject the null hypothesis, even when it's false. This increases the probability of a Type II error, thus potentially reducing the power of the test. The power curve will shift to the left.

b. If the sample size is reduced from 90 to 50, the effect on the power curve is that it will also shift towards the left.

What more should you know about decreasing the alpha and the power curve?

The power curve is a graph that shows the probability of rejecting the null hypothesis as a function of the true value of the mean.

In the given scenarios of this study, Reducing the significance level and reducing the sample size will shift the power curve to the left, indicating a decrease in the statistical power of the test.

The power of a statistical test is the probability that it correctly rejects the null hypothesis when the alternative hypothesis is true.

a) Reducing alpha from 0.05 to 0.01 means that we are more stringent in our assessment of whether the new treatment is effective.

This will result in a decrease in the power of the test, meaning that it is less likely that we will be able to detect a difference between the new treatment and the previous treatment.

b) If the sample size is reduced from 90 to 50, the effect on the power curve is that it will also shift towards the left.

This is because a smaller sample size decreases the power of the test. A larger sample size provides more information and thus makes it more likely to correctly reject the null hypothesis when the alternative hypothesis is true.

Therefore, by reducing the sample size, you are decreasing the likelihood of detecting a true effect if one exists, thus reducing the power of the test.

2Al + Cr203 + Al203 + 2Cr

The reaction of 44.1 g of Cr203 with 35.0 g of Al produced 25.6 g of Cr. What is the percent yield for

Answers

To determine the percent yield, we need to first calculate the theoretical yield of the reaction using stoichiometry, and then divide the actual yield by the theoretical yield and multiply by 100%. The percent yield of the reaction is approximately 84.9%.

What is percent yield?

Percent yield is a measure of the efficiency of a chemical reaction, calculated by dividing the actual yield of a reaction by the theoretical yield and multiplying by 100%. It represents the percentage of the theoretical amount of product that was actually obtained in a reaction.

The balanced chemical equation is:

2Al + Cr₂O₃ → Al₂O₃ + 2Cr

The molar mass of Cr₂O₃ is 152 g/mol, the molar mass of Al is 27 g/mol, and the molar mass of Cr is 52 g/mol.

We need to determine which reactant is limiting, so we can calculate the theoretical yield based on the amount of limiting reactant. We can do this by calculating the number of moles of each reactant using their molar masses and dividing by their stoichiometric coefficients in the balanced equation:

moles of Cr₂O₃= 44.1 g / 152 g/mol = 0.29 mol

moles of Al = 35.0 g / 27 g/mol = 1.30 mol

From the balanced equation, we see that 1 mole of Cr2O3 reacts with 2 moles of Cr. Therefore, the theoretical yield of Cr is:

moles of Cr produced = 0.29 mol Cr₂O₃x (2 mol Cr / 1 mol Cr₂O₃) = 0.58 mol Cr

mass of Cr produced = 0.58 mol Cr x 52 g/mol = 30.16 g Cr

The percent yield is:

% yield = (actual yield / theoretical yield) x 100%

% yield = (25.6 g Cr / 30.16 g Cr) x 100% = 84.9%

Therefore, the percent yield of the reaction is approximately 84.9%.

before any reaction occurs, the concentrations of a and b in the reaction below are each 0.0420 m; the concentration of c is 0 m. what is the equilibrium constant if the concentration of a at equilibrium is 0.0124 m?

Answers

The equilibrium constant for this reaction is 0.096.

The equilibrium constant (Kc) for the following reaction is given by the ratio of the concentration of products to the concentration of reactants at equilibrium, with each concentration raised to the power of its coefficient in the balanced chemical equation:

a + b ⇌ c

Kc = [c]/([a][b])

At the beginning, the concentrations of a and b are 0.0420 M, and the concentration of c is 0 M. At equilibrium, the concentration of a is 0.0124 M. We can assume that the concentration of b at equilibrium is also 0.0124 M, since the stoichiometry of the reaction tells us that the ratio of a to b is 1:1.

Therefore, we can plug these values into the equilibrium constant expression:

Kc = [c]/([a][b]) = 0.0124^2 / (0.0420)(0.0420) = 0.096

So, the equilibrium constant for this reaction is 0.096.

Humid air at 100 kPa, 20°C, and 90 percent relative humidity is compressed in a steady-flow, isentropic compressor to 880 kPa. What is the relative humidity of the air at the compressor outlet? The specific heat ratio of air at room temperature is k = 1.4. Use data from the tables. Solve using appropriate software. P kPa Humid air 1 100 kPa 20°C, 90% The relative humidity at the exit is %

Answers

The relative humidity at the compressor outlet is about 122

The psychrometric chart, which shows the properties of moist air. The chart is based on the relationships between temperature, pressure, and specific humidity, which is the mass of water vapor in a unit mass of dry air.

Using the given data, we can find the initial properties of the air from the chart:

At 100 kPa and 20°C, the specific humidity of the air is about 0.009 kg/kg.

At 90% relative humidity, the dew point temperature of the air is about 18°C.

Next, we can use the isentropic compression process to find the final properties of the air:

Since the compression is isentropic, the entropy of the air remains constant during the process.

From the definition of entropy, we know that the entropy of the air is proportional to its specific volume raised to the power of the specific heat ratio k.

Therefore, if we know the specific volume of the air at the initial and final states, we can use the specific heat ratio to find the ratio of the specific volumes.

From the tables, we can find that the specific volume of the air at 100 kPa and 20°C is about 0.877 m3/kg.

To find the specific volume at 880 kPa, we can use the ideal gas law with a constant specific heat:

v2 = (R T2) / P2

= (R T1) / (P1 (P2 / P1)^(1/k))

= v1 / (P2 / P1)^(1/k)

where

R = 287 J/kg-K is the gas constant for air

T1 = 20°C + 273.15 = 293.15 K is the initial temperature

P1 = 100 kPa is the initial pressure

P2 = 880 kPa is the final pressure

k = 1.4 is the specific heat ratio

v1 = 0.877 m3/kg is the initial specific volume

Plugging in the numbers, we get:

v2 = 0.877 / (880 / 100)^(1/1.4)

= 0.240 m3/kg

Now we can use the chart again to find the final properties of the air:

At 880 kPa and 20°C, the specific volume of the air is about 0.240 m3/kg.

We can follow the constant-enthalpy line on the chart from the initial state until we reach the final specific volume.

The intersection of the constant-enthalpy line and the final specific volume line gives us the final state of the air.

We can read off the final specific humidity and dew point temperature from the chart.

Using the chart, we find that the final specific humidity is about 0.028 kg/kg, and the dew point temperature is about 29°C.

Finally, we can use the definition of relative humidity to find the relative humidity at the compressor outlet:

RH2 = (W2 / Ws(T2)) * 100%

where

W2 = 0.028 kg/kg is the final specific humidity

Ws(T2) = 0.023 kg/kg is the saturation specific humidity at 29°C

RH2 = ? is the relative humidity at the compressor outlet

Plugging in the numbers, we get:

RH2 = (0.028 / 0.023) * 100%

= 121.7%

Therefore, the relative humidity at the compressor outlet is about 122

The relative humidity at the exit is approximately 8%.

To solve this problem, we need to use the psychrometric chart, which provides information about the properties of moist air. First, we locate the initial conditions of the air on the chart, which corresponds to a point with a temperature of 20°C, a pressure of 100 kPa, and a relative humidity of 90%. Then, we draw a straight line on the chart to represent the isentropic compression process to a final pressure of 880 kPa. Finally, we locate the final state of the air on the chart, which corresponds to a point with a temperature of approximately 118°C and a relative humidity of approximately 8%.

The decrease in relative humidity is due to the fact that as the air is compressed, its temperature increases, and its absolute humidity (mass of water vapor per unit volume of air) remains constant, which leads to a decrease in the relative humidity (ratio of the mass of water vapor in the air to the maximum mass of water vapor that the air can hold at that temperature and pressure).

There will be an actual yield of 0.73L and about 1.01 g of sodium hydrogen carbonate- to create 425 mL of CO2.

How to explain the yield

The theoretical yield of CO2, which can be calculated by the following equation, is 0.77 liters:

 (2.5 g NaC2H3O2) / (82.03 g/mol NaC2H3O2) x (1 mol CO2 / 1 mol NaC2H3O2) x (22.4 L/mol at STP).

For determining the actual yield of CO2, the mass produced ought to be known. Suppose it was 1.5g. Then, this excerpt explains how the actual yield is measured:

    Actual yield = (1.5 g CO2) / (44.01 g/mol CO2) x (22.4 L/mol at STP),

         giving us an actual yield of 0.73L.

If 425mL of CO2 are expected to be formed, then the amount of sodium hydrogen carbonate required can be determined as follows:

The molar ratio for sodium hydrogen carbonate to CO2 is 1:1 and thus, in order to generate 0.53g of CO2, 0.012 mol of NaHCO3 should be taken into consideration.

Once the molar mass of NaHCO3, 84.01 g/mol, is taken note of, then we have the amount needed - i.e., 1.01 g of sodium hydrogen carbonate- to create 425 mL of CO2.

_________is the amount of a radiactive element required to sustain a chain reaction.

Answers

Critical mass is the amount of a radioactive element required to sustain a chain reaction.

The term used to describe the amount of a radioactive element required to sustain a chain reaction is "critical mass." Critical mass is a term used in nuclear physics that refers to the minimum mass of fissionable material needed to maintain a self-sustaining nuclear chain reaction. A chain reaction occurs when a neutron hits a nucleus, which then splits and releases more neutrons, leading to a cascade of nuclear reactions. Critical mass is determined by various factors such as the physical and chemical properties of the fissile material, its shape, temperature, and density. If too little of a fissile material is present, the neutrons will escape, and the reaction will stop.

If too much material is present, the reaction will become uncontrollable and lead to a nuclear explosion. Critical mass refers to the smallest amount of fissile material required to maintain a chain reaction. In order for a chain reaction to occur, a certain number of neutrons must be present. This number of neutrons is known as the neutron population, and it must be maintained at a certain level to keep the reaction going. This is accomplished by carefully controlling the amount of fissile material that is present. If there is too little fissile material, the neutron population will quickly drop below the critical level, and the reaction will stop.

If there is too much fissile material, the neutron population will grow uncontrollably, leading to a nuclear explosion. In order to maintain a chain reaction, the fissile material must be in a critical state, meaning that the neutron population remains constant over time. This is achieved by controlling the geometry of the fissile material, as well as its temperature and density. If any of these parameters change, the critical state will be lost, and the reaction will either stop or become uncontrolled. Therefore, critical mass is a crucial concept in the design and operation of nuclear reactors and weapons.

with an atomic number of 11, which of these elements gets its symbol from the latin word natrium?

Answers

The element with an atomic number of 11 that gets its symbol from the Latin word "natrium" is Sodium. Its symbol is "Na".

The symbol for sodium is Na, which is derived from the Latin word natrium. Sodium is a soft, silvery-white, highly reactive metal that is a member of the alkali metal group. It is an important element for many biological processes and is commonly found in salt (sodium chloride).

The other elements listed in the question are chlorine, iron, and nitrogen. Chlorine has an atomic number of 17, iron has an atomic number of 26, and nitrogen has an atomic number of 7. None of these elements gets their symbol from the Latin word natrium.

The products of photosynthesis are carbon dioxide (CO2) and water (H2O). O True False T/F: Upwelling of deep, cold, nutrient-rich waters is the only way for nutrients to reach coastal surface waters O True O False True/False: High Pressure systems in the Southern Hemisphere rotate clockwise True False

Answers

(A) The statement "the products of photosynthesis are carbon dioxide (CO₂) and water (H₂O)" is false.

(B) The statement "Upwelling of deep, cold, nutrient-rich waters is the only way for nutrients to reach coastal surface waters " is true.

(C) The statement "Pressure systems in the Southern Hemisphere rotate clockwise" is false.

(A) The products of photosynthesis are not carbon dioxide (CO₂) and water (H₂O). Rather, they are glucose (C₆H₁₂O₆) and oxygen (O₂). During photosynthesis, plants and other photosynthetic organisms use sunlight, carbon dioxide from the atmosphere, and water from the environment to produce glucose and oxygen. This process occurs in the chloroplasts of plant cells.

(B) Upwelling of deep, cold, nutrient-rich waters is indeed one of the ways for nutrients to reach coastal surface waters. Upwelling refers to the upward movement of deep ocean waters to the surface. In many coastal areas, particularly along the western coastlines of continents, winds and ocean currents cause the upward movement of cold, nutrient-rich waters from the ocean depths to the surface. This process brings essential nutrients such as nitrates and phosphates to the surface, which promotes the growth of phytoplankton and supports productive coastal ecosystems.

(C)  High-pressure systems in the Southern Hemisphere do not rotate clockwise. In the Southern Hemisphere, high-pressure systems rotate counterclockwise due to the Coriolis effect. The Coriolis effect is a result of the Earth's rotation, causing moving objects, including air masses, to be deflected to the left in the Southern Hemisphere. This deflection leads to counterclockwise circulation around high-pressure systems and clockwise circulation around low-pressure systems in the Southern Hemisphere. In the Northern Hemisphere, the circulation is reversed, with high-pressure systems rotating clockwise and low-pressure systems rotating counterclockwise due to the same Coriolis effect.

2.65 g of sodium carbonate was dissolved in water and made up to 500 ml in a standard flask. 20 ml portions of this solution required 18.50 ml of a solution of hydrochloric acid when titrated using methyl orange indicator.

calculate:
(i) the concentration of the standard sodium carbonate solution in mol/l.
(ii) the concentration of the hydrochloric acid in mol/l.

Answers

(i) The concentration of the standard sodium carbonate solution is 0.05 mol/l.

(ii) The concentration of the hydrochloric acid is 0.0925 mol/l.


To solve this problem, we'll need to use the formula for molarity, which is defined as the number of moles of solute per liter of solution.

First, let's find the concentration of the standard sodium carbonate solution in mol/L. We know that the solution contains 2.65 g of sodium carbonate and has a volume of 500 mL. We also know that the molar mass of sodium carbonate is 106 g/mol. We can use this information to calculate the number of moles of sodium carbonate in the solution:

2.65 g sodium carbonate / 106 g/mol = 0.025 mol sodium carbonate

The concentration of the solution in mol/L is equal to the number of moles of solute divided by the volume of the solution in liters. We can convert the volume of the solution from mL to L by dividing by 1000:

Concentration = 0.025 mol / (500 mL / 1000 mL/L) = 0.05 mol/L

Now let's find the concentration of the hydrochloric acid in mol/L. We know that 20 mL portions of the sodium carbonate solution required 18.50 mL of hydrochloric acid when titrated using a methyl orange indicator. We also know that the volume of hydrochloric acid used was 18.50 mL and the volume of the sodium carbonate solution was 20 mL.

We can use this information to calculate the concentration of the hydrochloric acid:

Concentration = (Volume of hydrochloric acid / Volume of sodium carbonate solution) * Concentration of sodium carbonate solution

= (18.50 mL / 20 mL) * 0.05 mol/L = 0.0925 mol/L

Therefore, the concentration of the standard sodium carbonate solution is 0.05 mol/L and the concentration of the hydrochloric acid is 0.0925 mol/L.

The total internal energy of an ideal gas is 3770 J. If there are 3 moles of the gas at 1 atm, what is the temperature of the gas

Answers

The temperature of the gas is approximately 100.8 K. To find the temperature of an ideal gas, we'll use the formula for the internal energy of an ideal gas (U) and the ideal gas law. The given terms are the internal energy (U = 3770 J), the number of moles (n = 3 moles), and the pressure (P = 1 atm, which is approximately 101325 Pa).

First, we'll use the internal energy formula for an ideal gas: U = (3/2)*nRT, where R is the universal gas constant (8.314 J/mol·K). We're solving for the temperature (T), so we'll rearrange the formula to isolate T:

T = (2/3)*(U / nR)

Now, plug in the given values:
T = (2/3)*(3770 J / (3 moles × 8.314 J/mol·K))
T = (2/3)*(3770 J / 24.942 J/mol·K)
T = (2/3)*(151.213 K)
T = 100.809 K

Therefore, the temperature of the gas is approximately 100.8 K. This calculation assumes the gas behaves ideally and allows us to determine the temperature given the internal energy, number of moles, and pressure.
