SOLUTION

TO DETERMINE

The average of 212, 215, 218, 221, 224

EVALUATION

Here the given observations are

212, 215, 218, 221, 224

Total number of observations = 5

Sum of the observations

= 212 + 215 + 218 + 221 + 224

= 1090

Hence the required average

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

$\displaystyle \sf{ = \frac{1090}{5} }$

$= 218$
