Question (13) Assume there is a disease that afflicts 0.3% (0.003) of the population. A test exists to diagnose the disease. The sensitivity of the test is 100%, and the false positive rate is 3% (0.03). Sensitivity refers to the probability that somebody who has the disease is correctly diagnosed, while the false positive rate refers to the probability that somebody who does not have the disease is falsely diagnosed. What is the approximate probability that somebody who tests positive actually has the disease? 00.33 0.09 0.99 0.66 0.03 123
