Question

the ages of 10 workers at a factory are shown what is the mean absolute deviation for the group a 10 b 12.7 c 37.4 D 100 18 25 56 42 29 38 54 47 35 30 ​

Answer 1

10

Explanation:

Answer 2

The mean absolute deviation for the group is 10

Explanation:

The ages of 10 workers at a factory :

18 , 25 , 56 , 42 , 29 , 38 , 54 , 47 , 35 , 30 ​

`Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}\\\\Mean = (18+ 25 + 56 + 42 + 29 + 38 + 54 + 47 + 35 + 30 )/(10)\\\\Mean = 37.4`

`MAD =\frac{\sum_(i=1) ^n |x_i-\bar{x}|}{n}`

`MAD =(19.4+12.4+18.6+4.6+8.4+0.6+16.6+9.6+2.4+7.4)/(10)\\MAD=10`

Hence the mean absolute deviation for the group is 10
