Answer 2

The size of the class interval 250-300 is 50.

Given : The given class interval is 250-300

To find : The size of the given class interval.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the class size)

Here, we will be using the mathematical formula for calculating the class size. Which is :

Class size = Upper limit of the class - Lower limit of the class

In the given case,

• Upper limit of the class = 300
• Lower limit of the class = 250

By, putting the given values, we get :

Class size = 300-250 = 50

(This will be considered as the final result.)

Hence, the size of the class interval 250-300 is 50
