In a study of college athletes, the NCAA received anonymous responses from a random sample of 300 football players, 200 basketball players, and 100 baseball players. Asked whether they had used any banned performance enhancing drugs, 78 (26%) of the football players, 48 (24%) of the basketball players, and 36 (36%) of the baseball players said they had. Test the hypothesis that the proportion of athletes who would admit to using these drugs is the same for all three populations represented in the study. Use a significance level of 5%.
