The correct answer is (d), i.e., the correct hypotheses are as follows:

\(H_o: p_1 = p_2= p_3\)

against

\(H_1:\) At least one of the proportions is different from the others.

In hypothesis testing, the objective is to reject the null hypothesis that's why the null hypothesis is always set against the desired result.

In this problem, there are three categories given, each having its individual proportions: \(p_1\), \(p_2\), and \(p_3\) .

The null hypothesis is that all proportions are equal, i.e.,

\(H_o: p_1 = p_2= p_3\)

and the alternative hypothesis is that at least any one of the proportions is not equal to the others, i.e.,

\(H_1:\) At least one of the proportions is different from the others.

Thus, option (d) is correct.

Step-by-step explanation:

Given:

Angle LMN has a measure of 35°.

The angle is rotated 75° about point M to create angle L'M'N'.

To find:

The measure of angle L'M'N'.

Solution:

We have,

\(m\angle LMN=35^\circ\)

The angle LMN is rotated 75° about point M to create angle L'M'N'.

We know that, rotation is a rigid transformation. So, after rotation the corresponding sides and angles remains congruent.

It means,

\(m\angle L'M'N'=m\angle LMN\)

\(m\angle L'M'N'=35^\circ\)

Therefore, the measure of angle L'M'N' is 35°.

The experimental probability of selecting a green marble on the next attempt is 1/6 or approximately 0.1667 or 16.67%.

What is probability?

Probability is a measure of the likelihood of an event occurring.

The experimental probability of an event happening is calculated by dividing the number of times the event occurs by the total number of trials or attempts.

In this case, Diane has already selected 2 green marbles and 10 other marbles from the bag. So, the total number of marbles left in the bag is 12.

Since there are 2 green marbles left in the bag, the probability of selecting a green marble on the next attempt is:

2 (number of green marbles) / 12 (total number of marbles) = 1/6

So, the experimental probability of selecting a green marble on the next attempt is 1/6 or approximately 0.1667 or 16.67%.

The formula connecting E and F is E = k/F3, where k is a constant. This formula states that the value of E is inversely proportional to the cube of F.

That is, as F increases, the value of E decreases. For example, if F increases from 3 to 4, then the value of E decreases by a factor of 8.

This inverse proportionality between E and F3 is due to the fact that, as F increases, the cube of F increases at a faster rate. In other words, when F doubles, the cube of F increases by a factor of 8. This causes the value of E to decrease by the same factor of 8.

The formula is useful in many applications, such as in physics and engineering. For example, in physics, the formula can be used to calculate the force of an object in a gravitational field. The force is inversely proportional to the cube of the distance between the object and the center of gravity, where the constant k is equal to the gravitational constant. In engineering, the formula can be used to calculate the power of a motor, where the power is inversely proportional to the cube of the speed of the motor.

Overall, the formula E = k/F3 expresses the inverse proportionality between E and F3, and is used in various applications to calculate the value of E given the value of F.

Answer:

The third choice is correct

Step-by-step explanation:

Domain > or equal to -3, and range is less than or equal to -2

The right answer is: E, according to the Central Limit Theorem for proportionality. The statistic is inaccurate.

In probability theory, the central limit theorem establishes that, in many situations, when independent random variables are summed up, their properly normalized sum tends toward a normal distribution even if the original variables themselves are not normally distributed.

The Central Limit Theorem establishes that for a proportion p in a sample of size n:

The expected value is μ=р

The standard error is s=\(\sqrt{\frac{p(1-p)}{n} }\)

In this problem, the expected value is different of the expected of μ=р , hence, the statistic is biased, and the correct option is E.

1.6 * 7 = $11.20 for 7 pounds

The production manager should address the fact that the chips produced do not meet the desired specifications and take necessary actions to ensure compliance, which will impact sales and net profit.

In determining the company's ability to produce chips that meet specifications, the production manager should consider the 95% confidence interval for the mean length of the computer chips, which is (0.9 cm, 1.1 cm). This interval indicates that there is a 95% probability that the true mean length of the chips falls within this range. Since the desired specification is 1.2 cm, the production manager needs to assess whether the confidence interval includes the desired value.

In this case, the chips produced do not meet the desired specifications because the lower bound of the confidence interval is below 1.2 cm. The production manager should provide the vice-president with an explanation that acknowledges the deviation from the desired specification. However, they can also emphasize that the company has taken steps to control the production process, ensuring that most chips are within a close range of the desired specification. They can highlight that the 95% confidence interval provides a level of certainty about the population mean length of the chips.

The decision to produce chips that do not meet the desired specifications may impact the chip manufacturer's sales and net profit. The computer hardware company, being the largest customer, may consider switching to another supplier that can consistently meet the specification of 1.2 cm. This potential loss of sales can have a negative impact on the manufacturer's revenue and profitability. The production manager should emphasize the importance of addressing the issue to retain the customer, maintain sales volume, and sustain the company's financial performance.

Answer:

Please read the assumptions that lead to the proposed answer of options a, b, and e being correct.  Options c and d are easily rejected.  The question is ambiguous about the locations of the angles.

Step-by-step explanation:

Parallel lines have slopes that are identical.  Lines p and q have the same slopes.

It is difficult imagining what angles are represented by x, y, and z.  There are only 2 lines, and they do not intersect.  The locations of the angles are not identified.  The lack of an intersecting point means it is free range as to where we assign the angles.

The attached graph illustrates some possibilities for x, y, and z.  It uses two simple equations as examples, with the same slope to make them parallel.  Assinment of any angles requires the use of an imaginary line that intersects the two parallel lines.  Even then, there aren't many unique locations for the angles.  To illustrate the analysis, lets assign the angles x, y, and z to thelocations shown on the graph.  

Even with this huge step, there is limited information to be able to identify which of the answer options is correct.  We can say that:

x = z

x+y=180

y+z=180

The answer options (below) appear to have similar relationships, so let's agree that the use of the imaginary line, plus the locations of x, y, and z are valid.  Looking at the answer options, we can match choices a, b, and e to the conclusions above.  d makes no sense because it is not an equation.  c says that both lines must be perpendicular to the x axis, a limitation that is relatively immaterial to whether they are parallel.  The condition of being parallel depends on those two angles being the same (e.g., 45 and 45, 22 and 22, etc.) and not require that they both be 90.

Answer Options               Guarantee Parallel?

a. x = z                                     Yes

b. x + y = 180 degree              Yes

c. x + z = 180 degree              No

d. x + y                                     No

e. y + z = 180                           Yes

Assuming that x ≥ 0 and y ≥ 0, the situation is infeasible: True.

In Mathematics, these rules are generally used for writing and interpreting an inequality or system of inequalities that are plotted on a coordinate plane:

In this context, we can logically deduce that the given system of inequalities 5x+3y ≤ 15 and y ≥ 6 would not have a feasible solution set if they are subjected to x ≥ 0 and y ≥ 0:

Assuming the ordered pair (1, 2), we have:

y ≥ 6

2 ≥ 6 (False).

5x+3y ≤ 15

5(1) +3(2) ≤ 15

5 + 6 ≤ 15

11 ≤ 15 (True).

Therefore, it is not a feasible solution.

Step-by-step explanation:

From the given question.

We can write the null hypothesis & the alternative hypothesis as:

Null hypothesis:

\(\mathbf{H_o: \mu \leq 6}\)

Alternative hypothesis:

\(\mathbf{H_{a}:\mu >6}\)

From above, let's think about the type I error we could make and the type II error we could make.

Type I error:

The type I error at the null hypothesis showcases that the snow level is at 6 inches or below 6 inches, but we falsely concluded that the snow level is high above sea level.

Type II error:

Here, the snow level is literally above 6 inches, hence, we failed to conclude that the snow level is above 6 inches.

Thus, the consequences of the above analysis showcase that type II error has higher severe consequences because it may result in a situation that may endanger the passengers' safety.
