Sample of n subjects (where n is large) cross-classified according to disease status and screening test result are given below. Test Result Disease Positive(T) Negative(T) Total Present(D) 368 36 404 Absent(D) 12 384 396 Total 380 420 800 Assume P(D) = 0.002. Denote the probabilities of false negative and false positive, respectively by FNR and FPR. Then the sensitivity, specificity, FNR, FPR, and predicetive value positive of the screening test are, respectively, (Choose one from the following which is closest to the correct answer.) O a. 0.9697, 0.9109, 0.0303, 0.0891, 0.0568. O b. 0.9109, 0.9697, 0.0303, 0.0891, 0.0568. O e. 0.9697, 0.9109, 0.0891, 0.0303, 0.0568.
