Com E.g.: Doctors at a given hospital want to know if their heart surgery and recovery program allows for their patients to possess typical myocardial blood flow during bicycle exercise. The doctors take a random sample of 8 of their patients and measure their myocardial blood flow (MBF) during bicycle exercise. Their doctors know that healthy men should have an average myocardial blood flow (MBF) during bicycle exercise of 5.15. Here the doctors can use a one-sample t-test.
