Create an Excel spreadsheet that graphs the portfolio return and standard deviation combinations found in Problem 5.12 for Home Depot and Lowe's.

Data from Prob. 5.12

Use the table of annual returns in Problem 5.9 for Home Depot (HD) and Lowe’s (LOW) to create an Excel spreadsheet that calculates returns for portfolios that comprise HD and LOW using the following, respective, weightings: (1.0, 0.0), (0.9, 0.1), (0.8, 0.2), (0.7, 0.3), (0.6, 0.4), (0.5, 0.5), (0.4, 0.6), (0.3, 0.7), (0.2, 0.8), (0.1, 0.9), and (0.0, 1.0). Also, calculate the portfolio standard deviation associated with each portfolio composition. You will need to use the standard deviations found previously for HD and LOW and their correlation coefficient.
