The gold standard test for AMI checks for the presence of a chemical called troponin I to determine if an AMI occurred. Another test for AMI uses the chemical marker creatine kinase (CK). Below is a table that cross classifies the diagnosis of AMI by the troponin I test and the CK test in a sample of 510 subjects. Troponin | Test (Gold Standard). CK Test AMI No AMI AMI 68 43 No AMI 115 284 Suppose that the sample of 510 subjects above consisted of a random sample of men with chest pain between the ages of 50 and 60. The true proportion of men in the 50 to 60 age group who suffer from AMI is 8%. Is the following statement TRUE or FALSE? Based on this information, the positive predictive value of the CK test is 68 / (68 + 43). O True O False Screenshot
