While Tom Brady played until the age of 44 in the NFL, it has been documented that NFL players’ retirement age is normally distributed with a mean of 33 years and a standard deviation of 2 years, N (33, 2). a. What is the probability that an NFL player retires after the age of 35? Use Table A at the end of the textbook to answer this question. b. What is the probability that an NFL player retires between 30 and 36 years of age? Use Table A to answer this question. c. Find the age below which 75% of NFL players retire. Use Table A to answer this question.
While Tom Brady played until the age of 44 in the NFL, it has been documented that
NFL players’ retirement age is
deviation of 2 years, N (33, 2).
a. What is the probability that an NFL player retires after the age of 35? Use Table A
at the end of the textbook to answer this question.
b. What is the probability that an NFL player retires between 30 and 36 years of age?
Use Table A to answer this question.
c. Find the age below which 75% of NFL players retire. Use Table A to answer this
question.
d. Suppose the distribution of soccer players’ retirement age is N (30, 3). The soccer player
Andrea Pirlo retired at 38. How can you compare Pirlo’s and Brady’s longevity in their
sporting careers? Assuming they started their careers at the same age, determine who had
a longer career.
