If you increase the sample size from 25 to 100 while keeping the population standard deviation constant, what happens to the standard deviation of the sampling distribution of the mean?

Question

If you increase the sample size from 25 to 100 while keeping the population standard deviation constant, what happens to the  standard deviation of the sampling distribution of the mean?

Answer

It decreases by half, resulting in greater precision of the estimate.

Answer

It decreases by half, making the distribution wider.

Answer

It doubles, making the distribution wider.

Answer

It decreases to one-fourth of its original size, making the distribution much narrower.

Answer

It increases by a factor of 4, decreasing the precision of the estimate.
