Question

A normally distributed set of population scores has a mean of 65 and a standard deviation of 10.2. The mean of the sampling distribution of the mean, for samples of size 48 equals....

a. 1.47
b. 10.2
c. 65
d. non of the above

Answer 1

The mean of the sampling distribution of the mean is equal to the mean of the population, which is 65 in this case.

Step-by-step explanation:

The mean of the sampling distribution of the mean (also known as the central limit theorem) is equal to the mean of the population. In this case, the mean of the population scores is 65, so the mean of the sampling distribution of the mean, for samples of size 48, is also 65. Therefore, the correct answer is c. 65.
