Case study 3Screening for Antibody to the Human Immunodeficiency VirusBackground:In December 1982, a report in the MMWR described three persons who had developed acquired immunodeficiency syndrome (AIDS) but who had neither of the previously known risk factors for the disease: homosexual/bisexual activity with numerous partners and intravenous drug use. These three persons had previously received whole-blood transfusions.By 1983, widespread recognition of the problem of transfusion-related AIDS led to controversial recommendations that persons in known high-risk groups voluntarily defer from donating blood.In June 1984, after the discovery of the human immunodeficiency virus (HIV), five companies were licensed to produce enzyme-linked immunosorbent assay (EIA, then called ELISA) test kits for detecting HIV antibody. Blood bank directors were anxiously waiting to start screening blood with the new test until March 2, 1985, the date the first test kit was approved by the FDA.PART ITo help in the discussions, the State Epidemiologist turns to pre-licensure information regarding the sensitivity and specificity of EIA. The information indicates that the sensitivity of EIA is 95.0% (0.95) and the specificity is 98.0% (0.98).Question1a : With this information, by constructing a 2-by-2 table, calculate the predictive-value positive and predictive-value negative of the EIA in a hypothetical population of 1,000,000 blood donors. Assume that the actual prevalence of HIV antibody among blood donors is 0.04% (0.0004).Question1b: Using a separate 2-by-2 table, calculate predictive-value positive and predictive-value negative for a population of (0.95)1 drug users. Assume that the actual prevalence of HIV antibody among intravenous drug users is (0.95)2 (0.95)3.Question 2a: Do you think that the EIA is a good screening test for the blood bank? What would you recommend to the blood bank director about notification of EIA-positive blood donors?Question 2b: Do you think that the EIA performs well enough to justify informing test-positive clients in the drug abuse clinics that they are positive for HIV?Question 3: If sensitivity and specificity remain constant, what is the relationship of prevalence to predictive-value positive and predictive-value negative?

He rode a total of 14.4 miles that week. The next week, he rode to and from school 4 times and to and from his best friend's house 6 times. He rode a total of 14.4 miles that week, too.This system of equations can be used to represent the situation:5x+3y=14.44x+6y=14.4Which statement is correct?Choices:(A)In the system of equations, x represents the total distance Toby traveled to and from school each week, and y represents the total distance he traveled to and from his best friend's house each week.(B)In the system of equations, x represents the round-trip distance to and from Toby's best friend's house, and y represents the round-trip distance to and from Toby's school.(C)In the system of equations, x represents the round-trip distance to and from Toby's school, and y represents the round-trip distance to and from his best friend's house.(D)In the system of equations, x represents the total distance Toby traveled to and from his best friend's house each week, and y represents the total distance he traveled to and from his school each week.What was the total distance Toby traveled to and from school the first week?____ miles Get tutor helpAn apple orchard has 4 sections of different kinds of apple trees.
