Suppose the returns on bonds and T-bills are normally distributed. Based on the historical record in: Table 10 2 : use the NORMDIST function in Microsoft Excel to answer the following questions: (Do not round intermediate calculationis. Rid the final answers to 2 decimal places.) a. What is the probability that in any given year, the return on bonds will be greater than 10 percent? Less than 0 percent? b. What is the probability that in any given year, the return on T-bils will be greater than 10 percent? Less than 0 percent? c-1. In 1979, the return on bonds was - 283 percent. How likely is it that a return this low will recur at some point in the future? Probability c-2. T-bills had a retum of 11.01 percent in this same year. How likely is it that a return on T-bills this high will recur at some point in the future? Probability Return and Risk Statistics. 1957 to 2016
