Suppose the returns on long-term government bonds are normally distributed. Assume long-term government bonds have a mean return of 6.5 percent and a standard deviation of 9.8 percent.
What is the probability that your return on these bonds will be less than 13.1 percent in a given year? Use the NORMDIST function in Excel to answer this question. (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
Probability _______ %
What range of returns would you expect to see 68 percent of the time? (A negative answer should be indicated by a minus sign.
