Use the beef hot dog data in Exercise 7 of Sec. 8.5. Form 10,000 nonparametric bootstrap samples to solve this exercise.
a. Approximate a 90 percent percentile bootstrap confidence interval for the median calorie count in beef hot dogs.
b. Approximate a 90 percent percentile-t bootstrap confidence interval for the median calorie count in beef hot dogs.
c. Compare these intervals to the 90 percent interval formed using the assumption that the data came from a normal distribution.
