The probability that a person with certain symptoms has hepatitis is 0.7. The blood test used to confirm this diagnosis gives positive results for 95% of people with the disease and 5% of those without the disease. What is the probability that an individual who has the symptoms and who reacts positively to the test actually has hepatitis?

To diagnose colorectal cancer, the hemoccult test is conducted to detect occult blood in the stool. For symptom-free people over 50 years old who participate in screening using the hemoccult test, the following information is available. The probability that one of these people has colorectal cancer is 0.3 percent. If a person has colorectal cancer, the probability is 50 percent that he will have a positive hemoccult test. If a person does not have colorectal cancer, the probability is 3 percent that he will still have a positive hemoccult test. Imagine a person (over age 50, no symptoms) who has a positive hemoccult test in your screening. Your assignment is to use this hemoccult test scenario as an example to communicate the nature of a medical test to a lay person. (Think of a family member or a friend who is not familiar with statistics.) You need to incorporate three elements in your essay: Identify the base rate (or prevalence in medical literature), sensitivity (the…
