Parts (a) and (b) are the same as Exercise 2. Refer to Exercise 1, which gives exercise times for men and women in a class.

a. Create a five-number summary for the men's responses. Show how you found your answer.

b. Use your five-number summary to describe in words the exercise behavior of this group of students.

c. Draw a boxplot of the men's responses.

Exercise 1
This is the same as parts (a) and (b) of Exercise 3. Students in a statistics class 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

a. Compare the women to the men using a dotplot. What does your plot show you about the difference between the men and the women?

b. For each sex, determine the median response.

Exercise 2
Refer to Exercise 3.
a. Create a five-number summary for the women's responses. Show how you found your answer.

b. Use your five-number summary to describe in words the exercise behavior of this group of female students.

Exercise 3
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

a. Compare the women to the men using a dotplot. What does your plot show you about the difference between the men and the women?

b. For each sex, determine the median response.

c. Do you think there's a "significant" difference between the weekly amount that men and women exercise? Explain.
