Infectious Disease
Newborns were screened for human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) in five Massachusetts hospitals. The data [8] are shown in Table 4.15.
Table 4.15 Seroprevalence of HIV antibody in newborns’ blood samples, according to hospital category
Answer Problems 4.14 and 4.15 using an approximation rather than an exact probability.
4.14 If 500 newborns are screened at the inner-city hospital, then what is the exact binomial probability of exactly 5 HIV-positive test results?
4.15 If 500 newborns are screened at the inner-city hospital, then what is the exact binomial probability of at least 5 HIV-positive test results?
