Homework Answers

Answer #1

Expected return, variance and standard deviation = -5.10% , 2.95% , 17.19% respectively.

Option D is correct.

Expected Return :-

Probability Return of A Expected return
21% 6% 1.2600%
28% -29% -8.1200%
15% -15% -2.2500%
5% 12% 0.6000%
31% 11% 3.4100%
Expected Return -5.1%

Variance :-

Probability Return of A Deviation (Return- Expected return) square of Deviation Variance
21% 6% 11.100% 1.232% 0.25874%
28% -29% -23.900% 5.712% 1.59939%
15% -15% -9.900% 0.980% 0.14702%
5% 12% 17.100% 2.924% 0.14621%
31% 11% 16.100% 2.592% 0.80355%
Variance 2.95%

Standard deviation = square root ( variance) = (2.95%)1/2 = (0.0295)1/2 = 0.171898

Standard deviation =17.19%
