In the article "Prevalence and predictability of low-yield inpatient laboratory diagnostic tests" published in JAMA Network Open (Xu, 2019), the authors reported the prevalence, sensitivity, and specificity for diagnosing normal troponin I levels; troponin I is a marker for acute myocardial infarction. The authors reported a prevalence of 0.33, a sensitivity of 0.88, and a specificity of 0.79 for the lab test for troponin I levels. Determine the a. positive predictive value (PPV) for this test. b. negative predictive value (NPV) for this test. 14. According to the Medscape Today article "Standard care for pap screening" (Lie, 2003), the sensitivity and specificity of the pap smear test are at least 0.29 and 0.97, respectively. If the prevalence of cervical cancer is 0.01, determine a. the probability that a woman has a positive test result. b. the positive predictive value of the pap smear diagnostic test. c. the negative predictive value of the pap smear diagnostic test.
