Answer
Bell-shaped distribution.
Work Step by Step
Stems: 2, 3 and 4. There are three stems. If these stems represent one class each, we will have three classes for 85 numbers. The distribuition will look better if we split the stems. After this step, we have six classes: 2, 2, 3, 3, 4, 4. The first 2 represents the numbers from 20 to 24 and the second from 25 to 29, and so on.
The 6th class is empty. The peak is in the third class (the middle). The distribution is bell shaped.
