Consider three stock funds, which we will call Stock Funds 1, 2, and 3. Suppose that Stock Fund 1 has a mean yearly return of 19.70 percent with a standard deviation of 1770 percent. Stock Fund 2 has a mean yearly return of 16.90 percent with a standard deviation of 16.20 percent, and Stock Fund 3 has a mean yearly return of 26.80 percent with a standard deviation of 11.10 percent (e) For each fund, find an Interval in which you would expect 95.44 percent of all yearly returns to fail. Assume returns are normally distributed. (Round your answers to 2 decimal places. Negative amounts should be indicated by a minus sign.) Fund 1 Fund 2 Fund 3 (b) Using the intervals you computed in part a, compare the three funds with respect to average yearly returns and with respect to variability of returns Fund 1 has the Fund 2 has the Fund 3 has the average return and the average return and the average return and the variability vanability (c) Calculate the coefficient of variation for each fund, and use your results to compare the funds with respect to risk, Which fund is risklest? (Round your answers to 2 decimal places.) Fund 1 Coefficiant of Variation Fund 2 Coefficient of Vacation Fund 2 Coefficient of Variation Fund fis Fund 2 and Fundi least raky rakiest
