Suppose you want to test the notion that individuals perceive a greater height difference between men and women than actually exists, due to stereotyping. The true population difference between the height of men and women is an average of 5 inches. You obtain a random sample of 400 individuals and record their perceptions of the mean difference in height between men and women. You find that the sample perceives the difference between men and women to average 6 inches. The...
