STATS: I got it wrong, what's the right answer? What is the mean of the comparison distribution?
-
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? A. 60/100 = .60 B. 60 C. 64.5/100 = .645 D. 64.5 I put D and got it wrong, but after re-reading the book I think it's B. Is that correct? Please explain. Thanks! :)

Answer:
It's B, the mean of the comparison distribution is the same as the mean of the group.
