write down the formula for the mean:
solve for x
Once you have x, you can compue the coefficient of variation manually.
Hi I need your help. I can't work out how to find X. I know how to find the cofficient of the variation if I knew what X was.
If the following numbers have a mean of 5, find the value of x and find the coefficient of variation
5 x 2 x 9 11 1
