Solution

Class interval:
A class interval can be defined as the numerical width of any class in a particular distribution.
Mathematically, class interval $=$ Upper limit $-$ lower limit.
For example, the size of the class interval $30 - 26$ is $30 - 26 = 4$
Hence, class interval is upper limit $-$ lower limit.
