a. Using an excel spreadsheet and the calculations you have done above, prepare a spread sheet that provides the expected returns and the risk for a portfolio that invests in stock A and stock B. Prepare the calculations using 4% increments in the weights.
b. Using the excel spreadsheet and the information from part m, create a graph of your results. (If you have followed instructions and done the calculations correctly, your graph should look similar to the graph in Figure 13-5 on page 474 of the 9th edition.)
