Answer 1

Answer:

64

Step-by-step explanation:

Given In a cricket match the scores of the players are considered such that coefficient of variation of scores is 16 and mean is 25 . Then the variance is

We know that coefficient of variation is given by standard deviation / mean.

Let the standard deviation be x

 So coefficient of variation = standard deviation / mean x 100 in percent

                  16 = x / 25 x 100  

      So x = 4 %

Also variance is square of standard deviation.

 So variance is (4)^2 = 16%

                                           

           coefficient of variation = 64

Variance is square of standard deviation =
