Answer 2

Hey there!

____________________

In the question, the given class intervals is in the inclusive form, so we will convert into exclusive class intervals.

There are :

(0.5 - 10.5)

(10.5 - 20.5)

(20.5 - 30.5)

(30.5 - 40.5)

(40.5 - 50.5)

(50.5 - 60.5)

In order to draw a frequency polygon, we need to find the class marks.

Class mark of a class intervals

$= \large{ \mathsf{ \frac{upper \: limit + lower \: limit}{2} }}$
