Suppose the self-reports are completely accurate and are representative of the number of eighth-grade students who smoke in the general community. We are considering using an SCN level 2 100 µg/mL as a test criterion for identifying cigarette smokers. Regard a student as positive if he or she smokes one or more cigarettes per week. *3.68 What is the sensitivity of the test for light-smoking students (students who smoke ≤ 14 cigarettes per week)? *3.69 What is the sensitivity of the test for moderate-smoking students (students who smoke 15-44 cigarettes per week)? *3.70 What is the sensitivity of the test for heavy-smoking students (students who smoke > 45 cigarettes per week)? *3.71 What is the specificity of the test? *3.72 What is the PV of the test? *3.73 What is the PV of the test?
