Q. 35.0( 2 Votes )
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?
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 .
