 Consider historical data showing that the average annual rate of return on the S&P 500 portfolio over the past 85 years has averaged roughly 8% more than the Treasury bill return and that the S&P 500 standard deviation has been about 32% per year. Assume these values are representative of investors' expectations for future performance and that the current T-bill rate is 4%.  |

 Calculate the utility levels of each portfolio for an investor with A = 3. Assume the utility function is U = E(r) − 0.5 × Aσ2. (Do not round intermediate calculations. Round your answers to 4 decimal places.)  |
