Answer:A 5% Portfolio Standard deviation will be achieve if Frances invests 25% percents in diversified risky stocks and 75% risk free bonds
Explanation:
Portfolio weights = 25% risk free and 75% diversified risky stocks
Portfolio standard deviation = 15%
Portfolio Standard Deviation = weight of risky stocks x Total standard deviation
15% = 0.75 x total standard deviation
total standard deviation = 15%/0.75 = 20%
