Chapter 3.1, Problem 12E

During 2017, Gallup conducted a survey of adult Americans and asked the following question: What was the main reason you decided to enroll in the school or college where you completed your highest level of education? (“Why Higher Ed?,” Gallup, Inc., January 2018). The responses are summarized in the accompanying table.

1. a. Construct a pie chart to summarize these data.
2. b. Construct a bar chart to summarize these data.
3. c. Which of these charts—a pie chart or a bar chart—best summarizes the important information? Explain.

accompanying relative frequency table summarizes the responses for men and women.

1. a. Construct a comparative bar chart of the responses that allows you to compare the responses of men and women.
2. b. There were 8110 men and 15,260 women who responded to the survey. Explain why it is important that the comparative bar chart be constructed using the relative frequencies rather than the actual numbers of people (the frequencies) responding in each category.
3. c. Write a few sentences commenting on how college seniors perceive themselves with respect to physical health and how men and women differ in their perceptions.
