A researcher interested in relationships developed a questionnaire that measures the degree of affection adult men feel for their fathers. She has found that for the general population the distribution is skewed to the right, the mean degree of affection is 60, and the standard deviation is 16. The researcher now is wondering if men who themselves have just become new fathers will score higher on the scale than men in general. She samples a group of 100 new fathers and finds that their mean is 64.5.

Question

A researcher interested in relationships developed a questionnaire that measures the degree of affection adult men feel for their fathers. She has found that for the general population the distribution is skewed to the right, the mean degree of affection is 60, and the standard deviation is 16. The researcher now is wondering if men who themselves have just become new fathers will score higher on the scale than men in general. She samples a group of 100 new fathers and finds that their mean is 64.5.

What is the mean of the comparison distribution?

Answer 1

This seems to answer the question you are asking.

"She samples a group of 100 new fathers and finds that their mean is 64.5."

Answer 2

To determine the mean of the comparison distribution, we will use the concept of sampling distribution. In this case, we are comparing the mean of the group of new fathers to the mean of the general population.

The mean of the comparison distribution is equal to the mean of the general population, which is given as 60. Therefore, the mean of the comparison distribution is 60.
