Edna and Joel are arguing over two portfolio opportunities. Edna claims that portfolio 1, which has an expected return of 10 percent and a standard deviation of 20 percent, is better than is portfolio 2, which has an expected return of 16 percent and a standard deviation of 30 percent. Joel claims that portfolio 2 is "clearly" better. Edna claims Joel favors the more risky portfolio because he is a testosterone driven moron, and Joel claims Edna favors portfolio 1 because she is too much of a girly girl. Employing more sophisticated logic, and being careful to be kind to one another, explain why you think portfolio 1 is better than is portfolio 2 or why you think portfolio 2 is better than is portfolio 1 or why you are indifferent between the two portfolios.
