Consider historical data showing that the average annual rate of return on the 5&f50port folio over the past 85 yearshas averaged roughly 8% more than the Treasury bill return and that the 5&P500 standard deviation has been about 35% per year. Assume these values are representative of investors' expectations for future performance and that the current T-bill rate is 3%. Calculate the expected return and variance of portfolios invested in T-bills and the 5&S \& 50 index with weights as shown below. (Enter your answers as decimals rounded to 4 places.
