1.)Average Income for men and women confounded by working full-time or part-time. Suppose the average income for men is $20,000 (part-time) or $60,000 (full time). The average income for women is $20,000 (part-time) or $40,000 (full-time). Suppose that 80% of men work full-time (10% of women work full-time). What is the average income for these men? Pick the closest.

Select one:

a. $28,000

b. $36,000

c. $44,000

d. $52,000

e. $56,000

2).Suppose that the distribution of heights for men in the military is nicely symmetrical: mean=median=mode. Now suppose we mix in the heights of those few women in the military (who we expect would be shorter). If this combined distribution is skewed, is it left skew or right skew? The skew is the direction of the longer tail.

Select one:

a. Still symmetric

b. Left skew

c. Right skew
