False Positive Find the probability of selecting a subject with a positive test result, giventhat the subject does not have hepatitis C. Why is this case problematic for test subjects?18. False Negative Find the probability of selecting a subject with a negative test result, giventhat the subject has hepatitis C. What would be an unfavorable consequence of this error?19. Positive Predictive Value Find the positive predictive value for the test. That is, find theprobability that a subject has hepatitis C, given that the test yields a positive result. Does theresult make the test appear to be effective?20. Negative Predictive Value Find the negative predictive value for the test. That is, find theprobability that a subject does not have hepatitis C, given that the test yields a negative result.Does the result make the test appear to be effective?Question
