Choose the correct answer below. Based on the expected value, stock X should be chosen. However, stock X has a larger standard deviation, resulting in a higher risk, which should be taken into consideration. 0 Since the expected values are approximately the same, either stock can be invested in. However, stock X has a larger standard deviation, which results in a higher risk. Due to the higher risk of stock X, stock Y should be invested in. Since the expected values are approximately the same, either stock can be invested in. However, stockY has a larger standard deviation, which results in a higher risk. Due to the higher risk of stock Y, stock X should be invested in. Based on the expected value, stock Y should be chosen. However, stock Y has a larger standard deviation, resulting in a higher risk, which should be taken into consideration.
