A pharmaceutical company is running trials on a new test for anabolic steroids. The company uses the test on 500 athletes known to be using steroids and 400 athletes known not to be using steroids. Of those using steroids, the new test is positive for 495 and negative for 5. Of those not using steroids, the test is positive for 5 and negative for 395. A. What is the relative frequency of a false negative result (the probability that an athlete using steroids will test negative)? (Round your answer to two decimal places.) B. What is the relative frequency of a false positive result (the probability that an athlete not using steroids will test positive)? (Round your answer to two decimal places.)
