a$.$ Use the data to calculate annual rates of return for Bartman, Reynolds, and the Winslow $5000$ Index. Then calculate

each entity's average return over the $5-$year period. $($Hint: Remember, returns are calculated by subtracting the

beginning price from the ending price to get the capital gain or loss, adding the dividend to the capital gain or loss, and

dividing the result by the beginning price. Assume that dividends are already included in the index. Also, you cannot

calculate the rate of return for $2015$ because you do not have $2014$ data.$)$ Round your answers to two decimal places.
