The coefficient of variation of two distribution are 60% and 70%, and their standard deviations are 21 and 16 respectively. What is their arithmetic means?
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 .
