There are 25 students in the class.
Step-by-step explanation:
In order to find the number of students in the class, you can add the number of data points together.

There are three data points on 3, two data points on 4, five data points on 5, eight data points on 6, two data points on 7, one data point on 8, and four data points on 9, this means the total number of students will be 3 + 2 + 5 + 8 + 2 + 1 + 4 = 25 students, so this will be your answer.
