Question:

For each investment class in Table 3, assume that future returns are normally distributed with the population mean and standard deviation as given. Based on this assumption:

1. For each investment class, find the probability of a return that is less than zero (that is, find the probability of a loss). Is your answer reasonable for all investment classes? Explain.

2. For each investment class, find the probability of a return that is:

a. Greater than 5%.

b. Greater than 10%.

c. Greater than 20%.

d. Greater than 50%.

3. For which investment classes is the probability of the return greater than 50% is essentially zero? For which investment classes is the probability of such a return greater than 1 percent? Greater than 5%?

4. For which investment classes is the probability of loss is essentially zero?

5. For which investment classes is the probability of loss greater than 1%? Greater than 10%? Greater than 20%?
