Changing risk level. Mr. Malone wants to change the overall risk of his portfolio. ​ Currently, his portfolio is a combination of risky assets with a beta of 1.25 and an expected return of 14​%. He will add a​ risk-free asset​ (U. S. Treasury​ bill) to his portfolio. If he wants a beta of 1.00​, what percentage of his wealth should be in the risky portfolio and what percentage should be in the​ risk-free asset? If he wants a beta of 0.75​? If he wants a beta of 0.50​? If he wants a beta of 0.25​? Is there a pattern​ here?
