Answer 1

16.5

Explanation:

Given data to us is ,

• 20, 15, 14, 16, 17, 12, 20, 22 .

Arrange it in ascending order .

= 12 , 14 , 15 , 16 , 17 , 20 , 20 , 22

The middle most observation will be median in case n is odd and average of middlemost observations if n is even , that is n = 8 .

=> Middlemost observations = 16 , 17

=> Mean = 16 + 17 /2 = 33/2 = 16.5
