There are 3200 students at martinsville high school. there 575 students involved in athletics during the spring athletic seasons. what proportion best represents the percent of students not involved in athletics during the spring season? what percent of students is not involved in athletics?

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
