a.	Use the data to calculate annual rates of return for Bartman, Reynolds, and the Winslow
	5000 Index. Then calculate each entitys 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 2009 because you do not have 2008 data)
b.	Calculate the standard deviations of the returns for Bartman, Reynolds, and the Winslow
	5000. (Hint: Use the ample standard deviation formulate, Equation 8.2a in this chapter,
	which corresponds to the STDEV function Excel.)
c.	Calculate the coefficients of variation for Bartman, Reynolds, and the Winslow 5000.
d.	Construct a scatter diagram that shows Bartmans and Reynolds returns on the vertical
	axis and the Winslow 5000 Indexs returns on the horizontal axis.
e.	Estimate Bartmans and Reynolds betas by running regressions of their returns against
	the indexs returns. (Hint: Refer to Web Appendix8A.) Are these betas consistent with
	your graph?
f.	Assume that the risk-free rate on long-term Treasury bonds is 6.04%. Assume also that
	the average annual return on the Winslow 5000 is not a good estimate of the markets
	required return it is too high. So use 11% as the expected return on the market. Use the
	SML equation to calculate the two companies required returns.
g.	If you formed a portfolio that consisted of 50% Bartman and 50% Reynolds, what would
	the portfolios beta and required return be?
h.	Suppose an investor wants to include Bartman Industries stock in his portfolio. Stocks
	A, B, and C are currently in the portfolio; and their betas are 0.769, 0.985, and 1.423,
	respectively. Calculate the new portfolios required return if it consists of 25% of
	Bartman, 15% of Stock A, 40% of Stock B, and 20% of Stock C.
