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 over the past 24 hours. Here are the data:

a. Sunny was the student who sent 42 text messages. What is Sunny’s percentile?

b. Find the number of text messages sent by Joelle, who is at the 16th percentile of the distribution.
