Question:

According to a study by Nielsen Mobile, “Teenagers ages 13 to 17 are by far the most prolific texters, sending 1742 messages a month.” Mr. Williams, a high school statistics teacher, was skeptical about the claims in the article. So he collected data from his first-period statistics class on the number of text messages they had sent in the past 24 hours. Here are the data:

7 1 29 25 8 5 1 25 98 9. O 26 8 118 72 0 92 52 14 3 3 44 42


a. Make a boxplot of these data.

b. Use the boxplot you created in part (a) to explain how these data seem to contradict the claim in the article.
