You are asked to design a preventive intervention for Gastroenteritis, a very severe disease in Gainesville where early detection is crucial to avoid extreme medical complications and fatality as the disease progresses. The cost of screening and early treatment is much lower than the cost of treating late-stage disease. UF has developed a new version of the Gastroenteritis Screening Test called Test A. As part of the intervention, you will conduct a screening test to detect gastroenteritis among 15,600 individuals using the recently developed Test A. The disease prevalence of gastroenteritis in our study population is reported as 5.0%. Based on this information, the following is a 2×2 table depicting your study results for Test A: Test A   Gastroenteritis Present Gastroenteritis Absent Positive Test Result 585 2223 Negative Test Result 195 12597   The development team also provided you with the older original version of the test, which they labeled as Test B, as a potential alternative for your intervention. You decide to collect data on Test B to compare with the data you collected using Test A.  Based on this information, the following is a 2×2 table depicting your study results for Test B: Test B   Gastroenteritis Present Gastroenteritis Absent Positive Test Result 546 5187 Negative Test Result 234 9633   Note-If it is appropriate to report an answer value as a percentage and you would like to input your answer in percent format, you must include the % sign! Please round your answers to the nearest tenth decimal place (i.e, x.x%)    a. Calculate the sensitivity for Test A: [SensitivityA]  b. Calculate the specificity for Test A: [SpecificityA]  c. Calculate the sensitivity for Test B: [SensitivityB]  d. Calculate the specificity for Test B: [SpecificityB]  e. If we repeated this study using Test A and Test B in a new population that has a 40% prevalence of Gastroenteritis, we would see an increase in the [___] of the new population (compared to our first population with 5% prevalence of Gastroenteritis).  Choose your answer from either the PPV or NPV.
