Solution

Solution Steps

Step 1: Identify the Range of Each Class

The histogram shows the scores divided into classes.
Each class range is visible on the x-axis.

Step 2: Determine the Lower and Upper Boundaries of a Class

For example, the first class ranges from 70.5 to 75.5.

Step 3: Calculate the Class Width

Subtract the lower boundary from the upper boundary of a class.
For the first class: \( 75.5 - 70.5 = 5 \).

Final Answer

The class width for this histogram is 5.
