Because a new medical procedure has been shown to be effective in the early detection ofan illness, a medical screening of the population is proposed. The probability that the testcorrectly identifies someone with the illness as positive is 0.85, and the probability that the testcorrectly identifies someone without the illness as negative is 0.90. The incidence of the illnessin the general population is 0.002. You take the test and the result is positive. What is theprobability that you have the illness?

The probability that a person has a certain disease is 0.05. Medical diagnostic tests are available to determine whether the person actually has the disease. If the disease is actually present, the probability that the medical diagnostic test will give a positive result (indicating that the disease is present) is 0.92. If the disease is not actually present, the probability of a positive test result (indicating that the disease is present) is 0.04. a.
