Answer #1

Note : - the answer given for standard Deviation is wrong.

Expected Return = (- 4.287% + 5.655%) / 2

= 0.684%

Given Return X Expected Return X1 (X-X1)^2
-0.04287 0.00684 0.0024710841
0.05655 0.00684 0.0024710841
Total 0.0049421682

Standard Deviation = (0.0049421682 / 2)^1/2

= 4.971%
