Please help me solve this question:

Given the data here, a . a. Compute the average return for each of the assets from 1929 to 1940 (the Great Depression). b. Compute the variance and standard deviation for each of the assets from 1929 to 1940. 0. Which asset was riskiest during the Great Depression? How does that t with your intuition? Note: Notice that the answers for average return, variance and standard deviation must be entered in decimal format. 0 Data Table - >
