An investor with mean-variance preferences chooses to invest 70% of her wealth in a risky asset P with an expected rate of return of 15% and a standard deviation of 20%, and she puts 30% in a riskless Treasury bill that pays 5%. Let C denote this complete portfolio.

Draw the Capital Allocation Line (CAL) for this investor. Clearly label the points corresponding to the T-bill, asset P and portfolio.

What is the slope of the Capital Allocation Line (CAL)?
