State of Economy Probability Rate of return Strong 0.2 21% Normal 0.45 9% Weak 0.35 -5%Explanation / Answer
Part A:
Expected Return = 0.2 * 21% + 0.45 * 9% - 0.35 * 5%
Expected Return = 4.2% + 4.05% - 1.75%
Expected Return = 6.50%
Part B:
Standard Deviation2 = 0.2 * (21% - 6.5%)2 + 0.45 * (9% - 6.5%)2 + 0.35 * (-5% - 6.5%)2
Standard Deviation = 9.55%
Part C:
Coefficient of Variation = Standard Deviation/ Mean
Coefficient of Variation = 9.55%/ 6.50%
Coefficient of Variation = 1.47
