Chapter 1, Problem 1.22E

Students in a statistics class at Penn State were asked, "About how many minutes do you typically exercise in a week?” Responses from the women in the class were
   60, 240, 0, 360, 450, 200, 100, 70, 240, 0, 60, 360, 180,
     300, 0, 270
Responses from the men in the class were
   180, 300, 60, 480, 0, 90, 300, 14, 600, 360, 120, 0, 240

1. Compare the women to the men using a dotplot. What does your plot show you about the difference between the men and the women?
2. For each sex, determine the median response.
3. Do you think there’s a "significant" difference between the weekly amount that men and women exercise? Explain.
