Suppose the returns on long-term corporate bonds and T-bills are normally distributed. Based on the historical record, use NORMDIST function in Excel text to answer the following questions: Refer to Figure 12.10 a. What is the probability that in any given year, the return on long-term corporate bonds will be greater than 10 percent? Less than 0 percent? (Round your answers to 2 decimal places. (e.g., 32.16)) Greater than 10 percent Less than 0 percent 196 b. What is the probability that in any given year, the return on T-bills will be greater than 10 percent? Less than 0 percent? (Round your answers to 2 decimal places. (e.g., 32.16)) Greater than 10 percent Less than 0 percent c-1 In 1979, the return on long-term corporate bonds was -2.76 percent. How likely is it that such a low return will recur at some point in the future? (Round your answer to 2 decimal places. (e.g., 32.16)) Probability c-2 T-bills had a return of 10.56 percent in this same year. How likely is it that such a high return on T -bills will recur at some point in the future? (Round your answer to 2 decimal places. (e.g., 32.16) Probability
