Computation assignment - Sensitivity, Specificity, and Predictive Values A total of 250 study subjects were enrolled in a study to examine validity and performance of a new finger stick test for diabetes. A fasting glucose test (gold standard test) was given to diagnose diabetes. Please answer the following questions. Be sure to include your formulas (show your work)!
