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?
.60
To find the mean of the comparison distribution, we need to consider the mean of the general population and the mean of the sample of new fathers.
Given:
Mean of the general population (μ): 60
Mean of the sample of new fathers (M): 64.5
Since we are comparing the mean of the sample of new fathers to the mean of the general population, the mean of the comparison distribution will be the mean of the general population, which is 60.
Therefore, the mean of the comparison distribution is 60.
