According to CML equation, the market portfolio has an expected return (R_M) of 11% and standard deviation (_M) of 22%. You can borrow or lend at the risk-free rate of 3%. You want to create efficient portfolios thatll fall on the capital market line (CML or efficiency frontier) and be a combination of the market portfolio and risk-free asset. Assume that your risk tolerance, reflected by standard deviation of your portfolio, is 22%. Calculate how much would you invest in the market portfolio and risk-free asset (i.e., find weights of market portfolio and risk-free assets) to create your desired portfolio.

		WM =0.50, WRF=0.50
		WM =0.10, WRF=0.90
