multiple choice qu 9-23 (static) part j [lo 9-6]j. in attributes sampling, what effect does a decrease in the tolerable deviation rate have on sample size?

Answers

The tolerable deviation rate decreases, it necessitates a larger sample size to maintain the desired level of confidence and accuracy in the Sampling size.

In attributes sampling, the tolerable deviation rate refers to the acceptable level of non-conforming items or errors in a population. It represents the maximum rate of deviation or non-conformance that is considered acceptable for a given attribute or characteristic being inspected.

When the tolerable deviation rate is decreased, it means that a lower level of deviation or non-conformance is deemed acceptable. This has an effect on the sample size required for the attributes sampling.

Generally, a decrease in the tolerable deviation rate will lead to an increase in the required sample size. The reason for this is that when the acceptable level of deviation is reduced, it becomes more stringent, and a larger sample is needed to ensure that the observed deviation rate is statistically representative of the population.

By increasing the sample size, there is a higher likelihood of capturing a sufficient number of defective or non-conforming items to make reliable conclusions about the population's quality level. This helps to reduce the risk of accepting a batch or population that actually has a higher defect rate than what is considered tolerable.

the tolerable deviation rate decreases, it necessitates a larger sample size to maintain the desired level of confidence and accuracy in the sampling results. The increased sample size allows for a more precise estimation of the population's quality level, providing greater assurance in decision-making regarding acceptance or rejection of the population based on the observed deviation rate.

Bethany can mow her lamily's lawn in 4 hours. Her brother coin can mow the lawn into hoursWhich equation

Answers

Answer:

1/x = 1/4 + 1/3

Step-by-step explanation:

In 4 hours Bethany did the whole fraction 1 of the house.

In 1 hour he would do 1/4 of it.

In 3 hours Colin did the whole fraction 1 of the house.

In 1 hour he would do 1/3 of it.

In 1 hour they would both do (1/4 + 1/3)

If it takes both of them x hours to finish 1 whole fraction of the house.

In 1 hour they will both do 1/x

That means that:

1/x = 1/4 + 1/3

That is the equation. x can be solved for.

Calculate the frequency of light that has a wavelength of
4.25 x 10^-9m and a velocity of 300 m/s.

Answers

Answer:

The velocity of light, v, is the product of its wavelength, λ , and its frequency, f. This means that the wavelength is the velocity, v, divided by the frequency, f.

Wavelength of light = velocity of light / frequency of light

λ = v/f

λ = Wavelength of light, meters

v = Velocity of light (c = 3.0 x 108 m, for speed of light if not otherwise defined)

f = frequency of light, Hz

Answers

The sample size needed for the estimate to be within $500 with 90% confidence is 31.

We have,

To determine the sample size needed for the estimate to be within $500 with 90% confidence, we can use the formula:

Sample Size = (Z x Standard Deviation / Margin of Error) ²

In this case, the margin of error is $500, and we want a 90% confidence level, which corresponds to a Z-value of approximately 1.645 (obtained from a standard normal distribution table).

Substituting these values into the formula:

Sample Size = (1.645 x $9000 / $500) ²

Sample Size ≈ 30.071

Rounding up to the nearest whole number, the required sample size is 31.

Therefore,

The sample size needed for the estimate to be within $500 with 90% confidence is 31.

Answers

From the given information provided, the approximate volume of the cone is 94.24777 cubic inches.

The volume of a cone can be calculated using the formula V = (1/3) × π × r² × h, where "r" is the radius of the base of the cone, "h" is the height of the cone, and "π" is the mathematical constant approximately equal to 3.14159.

Radius r= 3 inches

Height h= 10 inches

π = 3.14159

Using the formula for the volume of a cone, V = (1/3) × π × r² × h, we can substitute the given values to calculate the volume of the cone:

V = (1/3) × 3.14159 × 3² × 10

I. Jack \& Jill each flip a fair coin twice. X is the maximum number of heads that one of them got. 1. Find the pdf for f 2. Find the conditional pdf for X given that X<2. 3. Find the conditional pdf given that Jill got exactly one head.

Answers

The pdf for X is given by P(X = 0) = 1/4, P(X = 1) = 1/2, and P(X = 2) = 1/4. When considering the condition X < 2, the conditional pdf for X = 0 is 1/3, and for X = 1 is 2/3. If Jill gets exactly one head, the conditional pdf for X = 0 is 0, and for X = 1 is 1.

The pdf for X:

Let's analyze the possible outcomes:

If both Jack and Jill get 0 or 1 head, X will be 0 or 1, respectively.

If one of them gets 2 heads, X will also be 2.

Hence, the pdf for X is:

P(X = 0) = 1/4

P(X = 1) = 1/2

P(X = 2) = 1/4

The conditional pdf for X given that X < 2:

Since X can only take the values 0, 1, or 2, we need to find the conditional probabilities for X = 0 and X = 1, given that X < 2.

P(X = 0 | X < 2) = P(X = 0) / [P(X = 0) + P(X = 1)] = (1/4) / [(1/4) + (1/2)] = 1/3

P(X = 1 | X < 2) = P(X = 1) / [P(X = 0) + P(X = 1)] = (1/2) / [(1/4) + (1/2)] = 2/3

The conditional pdf given that Jill got exactly one head:

If Jill gets exactly one head, there are three possible outcomes: HT, TH, and HH (H represents a head and T represents a tail). Out of these, only one outcome results in X = 1 (HH is excluded). Therefore, the conditional pdf for X = 1 given that Jill got exactly one head is 1. The conditional pdf for X = 0 given that Jill got exactly one head is 0, as it is not possible for X to be 0 in this scenario.

What is the connection string for SQL Server using Windows Authentication?

Answers

The connection string for SQL Server using Windows Authentication is as follows:

Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;

Specify the server address in the format "Server=myServerAddress". Replace "myServerAddress" with the name or IP address of the SQL Server instance you want to connect to.

Specify the name of the database you want to connect to in the format "Database=myDataBase". Replace "myDataBase" with the name of the database.

Use Windows Authentication by setting "Trusted_Connection=True". This means that the user running the application is authenticated using their Windows credentials, rather than a SQL Server login.

Use semicolons (;) to separate the different parts of the connection string.

Using Windows Authentication is a more secure and convenient way to connect to a SQL Server database, as it eliminates the need to store and manage login credentials in the application.

the z-score follows a normal distribution with 1 and 0, which is known as the standard normal distribution.

Answers

Yes, that is correct.

A z-score, also known as a standard score, is a measure of how many standard deviations a data point is away from the mean of a normal distribution. When the mean is 0 and the standard deviation is 1, the normal distribution is known as the standard normal distribution. Z-scores are useful for comparing data points from different normal distributions and for calculating probabilities in a standard normal distribution. For example, a z-score of 1.5 means that the data point is 1.5 standard deviations above the mean of the standard normal distribution.

Carlisle Transport had $4,520 cash at the beginning of the period. During the period, the firm collected $1,654 in receivables, paid $1,961 to supplier, had credit sales of $6,916, and incurred cash expenses of $500. What was the cash balance at the end of the period?

Answers

To calculate the cash balance at the end of the period, we need to consider the cash inflows and outflows.

Starting cash balance: $4,520

Cash inflows: $1,654 (receivables collected)

Cash outflows: $1,961 (payments to suppliers) + $500 (cash expenses)

Total cash inflows: $1,654

Total cash outflows: $1,961 + $500 = $2,461

To calculate the cash balance at the end of the period, we subtract the total cash outflows from the starting cash balance and add the total cash inflows:

Cash balance at the end of the period = Starting cash balance + Total cash inflows - Total cash outflows

Cash balance at the end of the period = $4,520 + $1,654 - $2,461

Cash balance at the end of the period = $4,520 - $807

Cash balance at the end of the period = $3,713

Therefore, the cash balance at the end of the period is $3,713.

6x = perimeter of the regular hexagon

The perimeter must be greater than 0.

Also, the perimeter must be less than or equal to 24. This is because of the phrasing "perimeter is at most 24 inches".

In other words, the perimeter is between 0 and 24, excluding 0 and including 24.
