Answer 1

Given : If the class mark of a class interval is 8.5. The class size is 5.

To find : The class limit of the corresponding class interval?

Solution :

Let the class mark, x=8.5

Class size, h=5

Lower limit is

is

L=x -h/2

L=8.5-5/2

L=8.5-2.5

L=6

Upper limit is

U=x+ h/2

U=8.5+ 5/2

U=8.5+2.5

U=11
