Answer 2

• We have to evaluate the above expression by using the given data.

           Given data:- $12,16,20,24,28.$

           To find:- Value of mean.

           Solution:-

• We know that mean is an arithmetic average of all numbers.

           $=>12,16,20,24,28.$

          $mean =\frac{\text { Sum of all number }}{\text { Total number of observation }}$

           Therefore

            $\begin{array}{l}\text { mean }=\frac{12+16+20+24+28}{5} \\\text { mean }=\frac{100}{5} \\\text { mean }=20 .\end{array}$

       Hence we will get the mean is $20.$
