Answer: The standard deviation of the sampling distribution of M is equal to the standard deviation of the population divided by the square root of the sample size.

You can assume that the sampling distribution of M is normally distributed for any sample size.

Step-by-step explanation:

According to the central limit theorem , if we have a population with mean $(\mu)$ and standard deviation $\sigma$ , then if we take a sufficiently large random samples from the population with replacement , the distribution of the sample means will be approximately normally distributed.
When population is normally distributed , then the mean of the sampling distribution = Population mean $(\mu)$
Standard deviation of the sampling distribution = $\dfrac{\sigma}{\sqrt{n}}$ , where $\sigma$ = standard deviation of the population , n= sample size.

So, the correct statements are:

You can assume that the sampling distribution of M is normally distributed for any sample size.
The standard deviation of the sampling distribution of M is equal to the standard deviation of the population divided by the square root of the sample size.

Natalka [10]

The check register is used to show the total amount Taquan spent

Using the assumed values, Taquan's initial balance is $1336.26

<h3>How to determine the amount before making the utility payment?</h3>

The question is incomplete, as the check register is not shown.

So, I will give a general explanation

Assume that the utility bill is $241.46

From the question, the new balance on March 24 is $1094.80

This means that the initial balance is:

Initial balance = New balance + Utility bill

This gives

Initial balance = $1094.80 + $241.46

Evaluate the sum

Initial balance = $1336.26

Using the assumed values, Taquan's initial balance is $1336.26
