Question

the household incomes for 10 different households sre shown what is the mean of absolute deviation for the group (round to the nearest tenth)6.412.715 252.2

Answer 1

Given the general rule for the mean of a data set of n elements:

`\mu=\Sigma^n_(i=1)(x_i)/(n)`

In this case, we have that n=10, then:

`\mu=(38+45+76+93+50+54+29+44+62+31)/(10)=(522)/(10)=52.2`

therefore, the mean is 52.2
