1 point
10
15
4.5
20
Other

Answer 1

Answer is 15.

Hope it will help you.

Answer 2

The Midpoint of given class interval = 15

Given:

Class of a frequency distribution contains a class with limits 10 and 20

To find:

The midpoint of class  

Solution:

Given that Class of a frequency distribution contains a class with limits 10 and 20  

⇒ the class interval = 10 - 20

Here 10 will be the lower limit  and 20 will be the upper limit

The midpoint or Class mark = (lower limit + upper limit)/2

The midpoint of the class interval 10 - 20  

= (10+20)/2 = 30/2 = 15

Therefore,

The Midpoint of given class interval = 15
