McCabe, Ricciardelli, and James (2007) recruited 107 men and 151 women to complete a series of surveys pertaining to factors such as body image and body satisfaction. Using the Body Image Satisfaction scale, where higher scores indicate greater satisfaction, they found that men scored19.104.55 (MSD),

whereas women scored16.845.66 (MSD)

on this scale. Assuming these data are normally distributed, answer the following questions.

(a) What is thez-score for 19.10 in the sample of data for men?

z=

(b) What is thez-score for 16.84 in the sample of data for women?

z=

(c) What can you say about these twoz-scores?

The firstz-score is greater than the second because 19.10, the mean for men, is greater than 16.84, the mean for women.

Thez-scores are the same because both scores are at the mean in their respective distributions.

The secondz-score is greater than the first because 5.66, the standard deviation for men, is greater than 4.55, the standard deviation for women.

The firstz-score is greater than the second because the sum of the mean and standard deviation for men is greater than that for women.
