Answer 2

SOLUTION

TO DETERMINE

The arithmetic mean of 16,9,12,20,8

EVALUATION

Here the given observations are

16,9,12,20,8

Sum of the observations

= 16 + 9 + 12 + 20 + 8

= 65

Number of observations = 5

Hence the required arithmetic mean

$\displaystyle \sf{ = \frac{Sum \: of \: the \:observations }{Total \: number \: of \: observations } }$

$\displaystyle \sf{ = \frac{65}{5} }$

$\displaystyle \sf{ =13 }$
