Consider historical data showing that the average annual rate of return on the TSX$/$S&P Composite Index portfolio over the past $60$ years has averaged roughly $8\%$ more than the Treasury bill return and that the TSX$/$S&P Composite Index 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 expected return and variance of portfolios invested in T$-$bills and the TSX$/$S&P Composite index with weights as follows. $($Enter your answers as decimals rounded to $4$ places. Leave no cells blank $-$ be certain to enter $"0"$ wherever required.$)$
