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?
the answer is 60 I know this for sure becuse it is the answer i used and got it right
To find the mean of the comparison distribution, we need to make an assumption about the population mean score for new fathers. Since the researcher wants to compare the mean score of new fathers with the mean score of the general population, we can assume that the mean score for new fathers is the same as the mean score for the general population, which is 60.
Therefore, the mean of the comparison distribution is 60.
