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 devation has been about 30% 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=3. Assume the utlity function is u=(r)0.5A2. (Negative omounts should be indicoted by a minus sign. Do not round intermediate calculations. Round your answers to 4 decimol places.) Answer is complete but not entirely correct
