Question: Let X = true disease status and D = having strep throat and D c = not having strep throat Let Y = test results

Let X = true disease status and D = having strep throat and Dc = not having strep throat

Let Y = test results and + = test detects strep throat and - = test does not detect strep throat.

if P(X = D) = .4343, P(X = D | Y = +) = .6735, and P(Y = - | X = Dc) = .7143

Calculate the sensitivity of the test, round your answer to at least 2 decimal places.

Let X = true disease status and D = having strep

P(Y = +).P(X = D/Y = +) Hint: P(X = D) P(X = D , Y = +) P(X = D) P(Y = +).P(X = D/Y = +) Hint: P(X = D) P(X = D , Y = +) P(X = D)
