2.4

Answer 8

set 1: mean: 55 , MAD : 10

Answer 9

set 2 : mean: 67, MAD : 10.4

Answer 10

Woah!!! the concept is totally new to me. Thanks for asking. It enlarges my knowledge to the field I never known before.

Answer 11

Answer 12

lol

Answer 13

Method: set 1 : find the mean out by (43+42+56+62+72)/5 = 55
find MAD by formula: \(\dfrac{1}{n}\sum_{i=1}^n |x_i-\bar x|\), where \(\bar x\) is the mean above, that is 55
Hence MAD=\(\dfrac{1}{5} [|43-55|+|42-55|+56-55|+|62-55|+|72-55|]=10\)
lalalalalala.... I know something new,

Answer 14

Do the same with set 2.

Answer 15

so the answer is 10

Answer 16

I gave you both of them above the method
1) 10
2) 10.4

Answer 17

so the answer is 10.4
