construct a 2 by 2 table, calculate predictive value positive and predictive value negative of the EIA in a hypothetical population of 1,000,000 blood donors. using a separate 2 by 2 table calculate PVP and PVN for a population of 1000 ill patients. Assume that the actual prevalence of S. heidelberg among blood donors is 0.04% (0.0004 ) and that of people who ate foster's chicken is 10.0% (0.10).

    Scenario 1: The prevalence (a + c in the table below) of previously undetected diabetes in a population to be screened is approximately 1.5% and it is assumed that 10,000 persons will be screened. The screening test will measure blood serum sugar content. A value of 180 mg/dl or higher is considered positive. The sensitivity (a) and the specificity (d) associated with this screening are 22.9% and 99.8% respectively. Questions 1-9: set up a two by two table with the...
