Question 1

PART A

Some professional football players seem to earn tremendous amounts of money. However, their careers as professional players are short. A random sample of 20 retired players showed a sample mean career length of 5.2 years with standard deviation 2.3 years. Find a 95% condence interval of the mean career length of all professional football players. (496,544) (4.13, 6.27) (419,621) (4.12, 6.28) Continue to consider Question 1. Interpret the condence interval in the context. We are 95% condent that the mean career length of all professional football players is between the lower limit and upper limit. About 95% of all professional football players have career length between the lower limit and upper limit. There is 95% probability that that the mean career length of all professional football players is between the lower limit and upper limit. With 95% condence, the mean career length of the sampled professional football players is between the lower limit and upper limit. One sports magazine reported that the average career length is less than 6 years. Did the confidence interval support this claim, with 95% confidence? O No, because 6 years is well above the confidence interval. O Yes, because 6 years is within the confidence interval. O No, because 6 years is within the confidence interval. O Yes, because 6 years is well above the confidence interval
