Question
The Elisa test for the human immunodeficiency virus (HIV) that causes AIDS has been used in the screening of blood donations. As with most medical diagnostics test, the ELISA test is not infallible. If a person actually carries HIV, experts estimate that this test gives a positive result 97.7% of the time (the number is called the sensitivity of the test. If a person does not carry HIV ELISA gives a negative result 92.6% of the time. Suppose that 0.5% of the public carries HIV.
Choose the appropriate statistical probability notation for the sentence.
If a person does not carry HIV, ELISA gives a negative result 92.6% of the time.
ChoiceA : P(noHIV) = .926
ChoiceB : P(-result) = .926
ChoiceC : P(noHIV|-result) = .926
ChoiceD : P(-result |noHIV) = .926
