1) From the following data, calculate the average annual return, the variance, standard deviation,and coefficient of variation for each asset.

B -6%, 20%, 2%, -5%, 10%

C 12%,15%, 17%

D 10%, -10%,20%, -15%,8%, -7%

2) Also, if possible based on above answer, can you explain to me which asset appears riskiest based on standard deviation? Based on coefficient variation.
