The data on hours of sleep discussed in Example 7.5 also included whether each student was male or female. Here are the separate five-number summaries for “hours of sleep” for the two sexes:
a. Two males reported sleeping 16 hours and one reported sleeping 12 hours. Using this information and the five-number summaries, draw boxplots that allow you to compare the sexes on number of hours slept the previous night. Use a format similar to Figure 7.10.
b. Based on the boxplots in part (a), describe the similarities and differences between the sexes for number of hours slept the previous night.
