An anti-doping agency decided to investigate if an athlete€™s eliteness was related to the likelihood of doping. It unexpectedly drug-tested the top 10 finishers in all the track and field events at a large meet. From this, it calculated the percentage of first-place finishers who tested positive, the percentage of secondplace finishers who tested positive, and so on. The agency then wanted to examine the relationship between the place in which an athlete finished and the likelihood of testing positive. What test should the agency use?
