Provide an appropriate response.Marcella is nearing retirement age and has some money to invest. She is deciding between Fund A which in the past has grown by a mean of 7% per year with a standard deviation of 2% and Fund B which has grown by a mean of 10% with a standard deviation of 6%. Which fund should she choose? Explain your thinking.
What will be an ideal response?
Fund A would be less risky. Fund B has a higher mean return but also a higher standard deviation indicating that there is more variation in its returns. Since Marcella is nearing retirement age, this is probably a short-term investment. Marcella won't have time to ride out the fluctuations and will not have much flexibility about when to withdraw her money. Of course she may be lucky with Fund B but if she wants more security, she should choose Fund A.
