Answer 1

Answer:

The coefficient of variation is the standard deviation divided by the mean and is calculated as follows: In this case µ is the indication for the mean and the coefficient of variation is: 32.5/42 = 0.77. This means that the size of the standard deviation is 77% of the size of the mean.
