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
