1,765 patients were given a positive/negative screening test for a disease. N = 415 patients tested positive N = 1,350 patients tested negative Due to constraints, not all 1,765 patients were given the definitive disease diagnostic test; clinicians had to pick a sample size (95% CL, 5% MoE) from the positive and negative groups. n = 200 patients tested positive n = 300 patients tested negative Does this mean that the True Positives (TP), FP, FN, and TN values have a +/ 5% MoE? So the 89% True Positives is 84 – 94%?
