A marathon was held in Washington D.C. Both Bethany and Mark ran in the marathon. The women's average time was 300 minutes with a standard deviation of 45 minutes. The men's average time was 215 minutes with a standard deviation of 45 minutes.

a. If Bethany ran the marathon in 400 minutes and Mark ran the marathon in 345 minutes, who did better relative to their gender? (hint: use z-scores!) b. What times for men would be outliers using the standard deviation criterion? c. What times for women would be outliers using the standard deviation criterion?
