The prevalence of a disease D among the population is 3%. There is a diagnostic test for disease D. The sensitivity of this test is 99%, this means that the test is positive given that the person has the disease. The specificity of this test is 98%, this means that the test is negative given that the person does not have the disease. a) Given that a person tests positive, what is the probability that the person does not have...

Table 1 below shows results obtained in a new screening test for diabetes. 10,000 people were screened. The cut-off level employed was 180mg of blood glucose per 100 ml. Everyone scoring above this level was classified as positive for diabetes. Everyone scoring below this level was classified as negative for diabetes. These results were compared to a “gold standard” test for diabetes that is considered to be completely valid. Compute and interpret the sensitivity, specificity, positive predictive value (PPV) and...
