How can I obtain thr predictive values for the given chart for letter c) i and ii.? The question asks for the positive and negative predictive value. 2. Let's bring in some hypothetical data from a pre-employment drug screening.Positive Test Result(drug use is indicated)44(true positive)Subject Uses Drugs(false negative)860(false positive)(true negative)(a) False positive Find the probability of selecting a subject with a positive testresult, given that the subject does not use drugs.Subject is Not a Drug UserNegative Test Result(drug use is not indicated)690(b) False negative Find the probability of selecting a subject with a negative testresult, given that the subject uses drugs.(c) Predictive valuei. Find the positive predictive value for the test. That is, find the probabilitythat a subject uses drugs, given that the test yields a positive result.ii. Find the negative predictive value for the test. That is, find the probabilitythat a subject does not use drugs, given that the test yields a negative result.

Given data: Positive Test result Negative Test result Total Uses Drugs 44 6 50 Not a Drug…

(c) Predictive value i. Find the positive predictive value for the test. That is, find the probability that a subject uses drugs, given that the test yields a positive result. ii. Find the negative predictive value for the test. That is, find the probability that a subject does not use drugs, given that the test yields a negative result.

(c) Predictive value i. Find the positive predictive value for the test. That is, find the probability that a subject uses drugs, given that the test yields a positive result. ii. Find the negative predictive value for the test. That is, find the probability that a subject does not use drugs, given that the test yields a negative result.
