MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A pharmaceutical company is running trials on a new test for anabolic steroids. The company uses the test on 400 athletes known to be using steroids and 200 athletes known not to be using steroids. Of those using steroids, the new test is positive for 365 and negative for 35. Of those not using steroids, the test is positive for 35 and negative for 165. 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.) C] What is the relative frequency of a faise positive result (the probability that an athlete not using steroids will test positive)? (Round your answer to two decimal places.)
