Class 11th RD Sharma - Mathematics 32. Statistics

Answer :

Here, the Coefficient of variation for the first distribution is 60

And, Coefficient of variation for the first distribution is 70

SD =21 and SD = 16

We know that, Coefficients variation =

So, Mean

For first distribution

Mean = 35

For the second distribution

Mean = 22.86

Hence, Means are 35 and 22.86 .
