Answer:

Ans 1)

As Average Annual return increases from Combination A to E we can observe that Standard deviation also increases from A to E

Therefore it is clear that there is positive relationship between the Risk of Caroline's portfolio and the average annual return.

Ans 2)

IF Caroline needs to reduce the risk associated with portfolio combination D from 15 to 5 then he can do 2 things such that he should sell some portion of portfolio invested into stocks and ultimately accept lower returns because as we see in Part 1) answer risk and returns are positively correlated.

Option 2) and Option 3) are correct

Ans 3)

95% confidence interval gives us range of -2*SD, 2*SD

therefore range of return for given scenario with portfolio return equals to 3.5% and SD=5%

(Mean- z value*SD , Mean value*SD)=

(3.5%-2*5% , 3.5%+2*5%)=(-6.5%,13.5%)

Gain of 13.5% and Loss of -6.5%
