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 .
