Who makes more: men or women? A manufacturing company is reviewing the salaries of its full-time employees below the executive level at a large
plant. The following histograms display the distri-
bution of salary for male and female employees:

(a) They were 756 female employees and 2451 male employees at the plant. Why did we use percents rather than counts on the vertical axis of these graphs?

(b) Do men or women tend to earn higher salaries at this plant? Justify your answer.
