Suppose a drug test is 80% sensitive and 92% specific. That is, the test will produce 80% true positive results for drug users and 92% true negative results for non-drug users. Suppose that 4.1% of people are users of the drug. If a randomly selected individual tests positive, what is the probability he or she is a user?

YOUR ANSWER SHOULD BE BETWEEN 0 AND 100 AND ROUNDED TO 4 DECIMAL PLACES.

(e.g. 59.5321 would be 59.5321%)
