Question

The probability that a person has a certain disease is 0.02. 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 0.01. a. If the medical diagnostic test has given a positive result​ (indicating that the disease is​ present), what is the probability that the disease is actually​ present? b. If the medical diagnostic test has given a negative result​ (indicating that the disease is not​ present), what is the probability that the disease is not​ present?

Answer 1

Answer:

If the false negative rate is 10% and the false positive rate is 1%, compute the probability that a person who tests positive actually has the disease. so about 65% of the people who test positive will have the disease.
