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 29.00 percent with a standard deviation of 19.10 percent; Stock Fund 2 has a mean yearly return of 12.20 percent with a standard deviation of 15.30 percent, and Stock Fund 3 has a mean yearly return of 17.10 percent with a standard deviation of 18.50 percent. a. For each fund, find an interval in which you would expect 95.44 percent of all yearly returns to fall. Assume returns are normally distributed.
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.
