Excel Activity: Evaluating Risk and Return dividends. Use a minus sign to enter negative values, if any. Download spreadsheet Evaluating_Risk and Return-146c88.xIsx two decimal places. b. Calculate the standard deviations of the returns 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 3%. Calculate the Sharpe ratios for Bartman, Reynolds, and the Index over this period using their average returns. Round your answers to four decimal places. e. Construct a scatter diagram that shows Bartman's and Reynolds's returns on the vertical axis and the Winslow 5000 Index's returns on the horizontal axis. Choose the correct graph. The correct graph is Stocks' Returns vs. Index's Returns f. Estimate Bartman's and Reynolds's betas by running regressions of their returns against the index's returns. Round your answers to four decimal places. Bartman's beta: Reynolds's beta: Are these betas consistent with your graph? These betas consistent with the scatter diagrams. Bartman's required return: % Reynolds's required return: % decimal places and for the portfolio's required return to two decimal places. Portfolio's beta: Portfolio's required return: % %
