A company administers a drug test to its job applicants as a condition of employment; if a person fails the drug test the company will not hire them. Suppose the drug test is 77% sensitive and 81% specific. That is, the test will produce 77% true positive results for drug users and 81% true negative results for non-drug users. Suppose that 7% of potential hires are use drugs. If a randomly selected job applicant tests positive, what is the probability he or she is a user? Use four decimals for your final answer. Include the 0 before the decimal place. E.g., 0.1234 A company administers a drug test to its job applicants as a condition of employment; if a person fails the drug test the company will not hire them.
