1. Investment A has an expected annual return of 15% and Investment B has an expected annual return of 12%. The standard deviation of Investment A's return is 10% while the standard deviation of Investment B is 5%. Based solely on standard deviation, which investment is less risky? Based solely on coefficient of variation, which investment is less risky?
