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

To determine the mean of the comparison distribution, we need to analyze the given information.

The mean degree of affection for the general population is provided and is equal to 60. However, we do not have the mean degree of affection for new fathers.

Since the researcher sampled a group of 100 new fathers and found that their mean score is 64.5, we can use this as an estimate for the mean degree of affection for new fathers. Therefore, the mean of the comparison distribution is 64.5.
