Use Bayes theorem to answer the following question. A screening test for Hepatitis B in blood donors has been determined to have a sensitivity of 0.97 and a specificity of 0.96. If the prevalence (what is exist) of hepatitis B in the Canadian population is 10 out of 1000 people what is the predictive value of this test for a positive result?

A new screening test for COVID-19 was administered to 1,000 adults at a large medical center in Texas. The results showed that 152 out of 160 diagnosed cases of COVID-19 were correctly identified by the screening test. Of the 840 individuals without COVID-19, the screening test correctly identified 714. Based upon this information: 1. Calculate the test's sensitivity, specificity, and the positive and negative predictive values. 2. Calculate the prevalence rate of COVID-19 in this population and the accuracy of...

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...
