3. Suppose a screening test has a sensitivity of 0.98 and a false-positive rate of 0.01. The test is used in a population that has a disease prevalence of 0.001. Determine the predictive value of a positive test under these circumstances. Pr (D | T) = Pr(DIT) Pr(TID) x Pr(D) [Pr(TID) x Pr(D)] + [Pr(TID) x Pr(D)] sensitivity X prevalence [sensitivity X prevalence] + [false positive rate 1 - prevalence]
