Suppose the returns on long-term corporate bonds and T-bills are normally distributed. Assume for a certain time period, long-term corporate bonds had an average return of 6.9% and a standard deviation of 9.9%. For the same period, T-bills had an average return of 5.4% and a standard deviation of 4.1%. Use the NORMDIST function in Excel to answer the following questions: 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? (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 given year, the return on T-bills will be greater than 10 percent? Less than 0 percent? (Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.) c. In one year, the return on long-term corporate bonds was -5.6 percent. How likely is it that such a low return will recur at some point in the future? T-bills had a return of 12.02 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? (Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)

Pls correct step by step explanation
Transcribed Image Text:Suppose the returns on long-term
corporate bonds and T-bills are normally
distributed. Assume for a certain time
period, long-term corporate bonds had an
average return of 6.9% and a standard
deviation of 9.9%. For the same period,
T-bills had an average return of 5.4% and a
standard deviation of 4.1%. Use the
NORMDIST function in Excel to answer the
following questions:
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? (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
given year, the return on T-bills will be
greater than 10 percent? Less than 0
percent? (Do not round intermediate
calculations and enter your answers as a
percent rounded to 2 decimal places, e.g.,
32.16.)
c. In one year, the return on long-term
corporate bonds was -5.6 percent. How
likely is it that such a low return will recur
at some point in the future? T-bills had a
return of 12.02 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? (Do not round intermediate
calculations and enter your answers as a
percent rounded to 2 decimal places, e.g.,
32.16.)
