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.
