immediate thumbs up. thanks!

Excel Activity: Evaluating Risk and Return Bartman Industries's and Reynolds Inc.'s stock prices and dividends, along with the Winslow 5000 Index, are shown here for the period 2015-2020. The Winslow 5000 data are adjusted to include dividends: The data has been collected in the Microsoft Excel file below. Download the spreadsheet and perform the required analysis to answer the questions below. Do not round intermediate calcolations. Use a minus sign to enter negative values, if any. Download spreadsheet Evaluating Risk and Return-7973. 5.1/5x 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 pcice 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 dato.) Round your answers to two decimal places. a.

Caiculate the standard deviations of the recarns for Bartman, Reynolds, and the Winslow 5000 . (Hint; Use the sample standard deviation formula, which corresponds to the STDEV.S function in Excel.) Round your answers to two decimal places. c. Calculate the coefficients of variation for Bartman, Reynolds, and the Winslow 5000. Round your answers to two decimal places. d. Assume the risk-free rate during this time was 2%. Calculate the Sharpe ratios for Bartman, Reynolds, and the Index over this period using their average retums. Round your answers to four decimal places.i Excel Activity: Evaluating Risk and Return Bartman Industries's and Reynolds Inc.'s stock prices and dividends, along with the Winslow 5000 Index, are shown here for the period 2015-2020.
