# Question

Refer to the alcohol consumption data in Exercise 29. Students were also asked if they typically sit in the front, back, or middle of the classroom. Here are the responses to the question about alcohol consumption for the students who responded that they typically sit in the back of the classroom:

Males (N = 22): 0, 0, 0, 0, 0, 0, 0, 1, 3, 3, 4, 5, 10, 10, 10, 14, 15, 15, 20, 30, 45, 55

Females (N = 14): 0, 0, 0, 0, 0, 1, 2, 2, 4, 4, 10, 12, 15, 17.5

a. Create a five-number summary for the males, and compare it to the one for all of the males in the class, shown in the Exercise 29. What does this say about the relationship between where one sits in the classroom and drinking alcohol for males?

b. Repeat part (a) for the females.

c. Create a stemplot for the males, and comment on its shape.

d. Create a stemplot for the females, and comment on its shape.

Males (N = 22): 0, 0, 0, 0, 0, 0, 0, 1, 3, 3, 4, 5, 10, 10, 10, 14, 15, 15, 20, 30, 45, 55

Females (N = 14): 0, 0, 0, 0, 0, 1, 2, 2, 4, 4, 10, 12, 15, 17.5

a. Create a five-number summary for the males, and compare it to the one for all of the males in the class, shown in the Exercise 29. What does this say about the relationship between where one sits in the classroom and drinking alcohol for males?

b. Repeat part (a) for the females.

c. Create a stemplot for the males, and comment on its shape.
