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 34\% per year. Assume these values are representative of investors' expectations for future performance and that the current T-bill rate is 2%. Calculate the expected return and variance of portfolios invested in T-bills and the S\&P 500 index with weights as shown below. Note: Round your "Expected Return" answers to 2 decimal places and "Variance" answers to 4 decimal places
