Q 6-6 the answers in there are wrong

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 38% per year. Assume these values are representative of investors' expectations for future performance and that the current T-bill rate is 5% Calculate the utility levels of each portfolio for an investor with A=2. Assume the utility function is U=E(r) - 0.5 A 2. (Do not round intermediate calculations. Round your answers to 4 decimal places. Negative amounts should be indicated by a minus sign. )
