Answer 1

Answer:

         " The Class Width of the given classes = 9 "

Step-by-step explanation:

→ It is a question of Statistics.

→ By class, we mean small sub-intervals of the total interval of the given data.

→ The class width is also known as class interval.

→ A class width is usually denoted by "h".

→ The formula to find the class width is

Class Width = Upper Class Limit - Lower Class Limit

Class Width = 30 -21 = 9      Or    40 - 31 = 9

So

       " Class Width = 9 "

I hope it will help you.
