In a particular country, 3% of the population is HIV positive. A test for HIV correctly diagnoses 95% of those who have the condition, but incorrectly diagnoses 4% of those who are not HIV positive as being HIV positive. A patient obtains a positive test result, apparently indicating the presence of HIV. Determine the probability that the patient is really HIV positive. Please round to three decimal places.

    (1) Suppose that the rate of HIV infection in the population is 0.1%. An HIV test is 99.8% accurate when administered to infected individuals, and 99.9% accurate when administered to non-infected individuals. Suppose that this test is administered to Patient X, and has a positive outcome, indicating that Patient X is infected. What is the probability that Patient X actually is infected with HIV?

    Question 2 1/1 pts 5% of a certain population has a particular genetic condition. A test for this condition gives a positive result with probability 20% when applied to a randomly selected individual from this population, and it gives a positive result 99% of the time, when the randomly selected individual really has the condition. Suppose a randomly selected individual from the population is tested. Given that the individual tests positive for the condition, what is the probability that the...

    [Base Rate Fallacy] Suppose a particular disease has a prevalence of 0.5 % people. A medical test to detect this disease has a false-positive rate of 5 % and diagnoses correctly every person who has the disease. What is the probability that a randomly selected person found to have a positive result actually has the disease? Give your answer to three decimal places.

    A test for the presence in the blood of antibodies to HIV, the virus that causes AIDS, gives a positive result with probability about 0.004 when a person who is free of HIV antibodies is tested. This is called a false positive. A clinic tests 5000 people who are all free of HIV antibodies. What is the probability that between 10 and 15 people in this sample will receive a false positive reading?

    Assume 50% of the world's population has a particular genetic condition. A blood test for the condition is available, but it is not 100% accurate. For those who do not have the genetic condition, the blood test will return a positive result 5% of the time. Additionally, for those who have the genetic condition, the test returns a negative result 8% of the time. Consider the experiment that an individual is randomly selected and tested for the genetic condition. Define...
