Suppose that Michael reads somewhere on the Internet that, on average, middle-aged people between 45 and 65 years old visit 9 different websites per day on weekend days. Michael knows that he cannot trust everything he reads on the Internet, so he decides to conduct his own study. He believes that the middle-aged people in his community visit more than 9 websites per day. He surveys a random sample of 14 middle-aged people in his community and asks them to look at their browsing history and count the number of different websites they visited last Saturday. The following stem and leaf plot shows the number of websites visited last Saturday by each person in the survey. The stem unit is tens and the leaf unit is ones.
