The Pap smear is the standard test for cervical cancer. The false-positive rate is .636; the false-negative rate is .180. Family history and age are factors that must be considered when assigning a probability of cervical cancer. Suppose that, after obtaining a medical history, a physician determines that 2% of women of his patient’s age and with similar family histories have cervical cancer. Determine the effects a positive and a negative Pap smear test have on the probability that the patient has cervical cancer.
