Suppose the returns on long-term government bonds are normally distributed. Assume long-term government bonds have a mean return of 6.1 percent and a standard deviation of 9.8 percent. What is the probability that your return on these bonds will be less than - 3.7 percent in a given year? Use the NORMDIST function in Excel to answer this question. What range of returns would you expect to see 95 percent of the time? What range would you expect to see 99 percent of the time
