Problem 10 to 20:
HIV Testing Accuracy rate is 99%. First, label the percentages in the table. Second, locate the areas in the table
that represents a false positive and a false negative test result.
Fact: HIV/AIDS also called: human immunodeficiency virus, acquired immunodeficiency syndrome.
HIV causes AIDS and interferes with the body's ability to fight infections.
In reality, a very small percentage of the population has HIV. If in USA, only about 0.5% of the population has
HIV, what percent of the population does not have HIV? Construct a 2 by 2 table and label the percentages
using 310,000,000 for population.
