Suppose the refums on long-term corporate bonds and T-bilfs are normally distributed. Assume for a certain time period, long-term corporate bonds had an average return of 6.8 percent and a standard deviation of 9.8 percent. For the same period. T-bilts had an average retum of 5.3 percent and a standatd devation of 4 percent. Use the NORMDIST function in the tho ansver the following questions: 0. What is the probability that in amy given year. the return on longterm corporate borids will be greatet than 10 percent? Less than O percent? Note: Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g. 32.16. b. What is the probability that in any glven year, the retum on fills will be greater than io percent? (ess than 0 percent? Note: Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g. 32.16. c. In ane yeat, the return on Iong term corporate bonts was 5.5 jercent. How likely is it that such a low retuen will recur at some point in the future? Tbills had a refum of 11.82 percent in the same year. How likely is it that such a high return on Tilils will recur at some point in the future? Note: Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.9. 32.16
