(Do not round intermediate calculations. Set your answers to four decimal places please.) Note: For a two stock portfolio: E(Rp)=rp =xr + x2r2 02 = x120,2 + x22022 + 2x1x2 P12 (102= Answers (Please work by hand, and show all your calculations, just for this part (A) a, b, and c), thanks)) a. Expected return = b. Variance = c. Standard deviation = B) How would your answer change if the correlation coefficient were 0 or -.3? Does this affect the portfolio level of risk, if so, how? (Round your answers to 2 decimal places.)? = a. Correlation coefficient b. Correlation coefficient = Standard deviation Standard deviation = C) Is Drake's portfolio better or worse than one invested entirely in share A, or is it possible to determine? Head's UP Please
