A study by the National Athletic Trainers Association surveyed random samples of 1679 high school freshmen and 1366 high school seniors in Illinois. Results showed that 34 of the freshmen and 24 of the seniors had used anabolic steroids. Steroids, which are dangerous, are sometimes used in an attempt to improve athletic performance. Researchers want to know if there's a difference in the proportion of all Illinois high school freshmen and seniors who have used anabolic steroids. Perform an appropriate hypothesis test using the 4-Step Process.
