Changing risk level. Ms. Chambers wants to change the expected return of her portfolio. Currently, she has all her money in U.S. Treasury bills with a return of 2.50%. She can switch some of her money into a risky portfolio with an expected return of 14%. What percentage of her wealth will she need to invest in the risky portfolio to get an expected return of 4% ? Of 6% ? Of 8% ? Of 10% ? Of 12% ? Of 14% ? Is there a pattern here? If she wants an expected return of 4%, then she should have % of her wealth in the risky portfolio and % in the risk-free asset. (Round both answers to two decimal places.)
