4 When the prevalence of a disease in the population is very low, such as HIV
infection or certain cancers, there is controversy about the benefits of screening
everyone for the disease. In this problem, you will see why this is the case.
The table below shows what is likely to happen if all roughly 300,000,000
Americans each were given an inexpensive enzyme immunoassay screening
test for HIV infection.
