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 variance on this questionnaire in the general population?

16
320
256
500

To calculate the variance of the questionnaire in the general population, we need to use the standard deviation and the skewness of the data.

Given that the standard deviation is 16, we know that the variance is the square of the standard deviation, which is 16 squared, equal to 256.

Therefore, the correct answer is 256.
