![A colonoscopy is a screening test for colon cancer, recommended as a routine test for adults over age 50. One study' provides the
best evidence yet that this test saves lives. The proportion of people with colon polyps expected to die from colon cancer is 0.01. A
sample of 2602 people who had polyps removed during a colonoscopy were followed for 20 years, and 12 of them died from colon
cancer. Does this provide evidence that the proportion of people who die from colon cancer after having polyps removed in a
colonoscopy is significantly less than the expected proportion (without a colonoscopy) of 0.01?
