Explanation:

Step1: Identify class - width formula

Class width = Upper - class limit - Lower - class limit.

Step2: Select a class interval

Let's take the first class interval \(0 - 2\). Here, the upper - class limit is \(2\) and the lower - class limit is \(0\).

$$2 - 0=2$$

We can also check with other intervals. For example, for the class interval \(3 - 5\), upper - class limit \(= 5\), lower - class limit \(= 3\), and \(5 - 3 = 2\).

Answer:

\(3\)
