A histogram is titled "Number of Students per Class" with number of students on the horizontal axis and frequency on the y-axis. Seven columns are plotted. The number of students ranges from 14 to 21 in increments of 1. The frequency ranges from 0 to 10 in increments of 1. The graph shows the following data: the frequency of 14 students is 4, the frequency of 15 students is 5, the frequency of 16 students is 3, the frequency of 17 students is 3, the frequency of 18 students is 4, the frequency of 19 is 0, the frequency of 20 students is 2, and the frequency of 21 students is 2.
