Individuals at risk for colon cancer are advised to have a colonoscopy beginning at age 50. The following table summarizes the results for a sample of 250 patients at risk for colon cancer: Colon cancer: yes Colon cancer: no Total x 50-x 50 Colonoscopy: yes Colonoscopy: Total no 5-x 195+x 200 5 245 250 In this table, x denotes the number of patients with colon cancer who had a colonoscopy. Suppose that we select one of the 250 patients at random. Find the value of a such that A and B are independent events, where A is the event that a patient has colon cancer, and B is the event that a patient has a colonoscopy. For this value of x, can we say that A' and B' are also independent events? A) x = 1. Yes, for x = 1, A' and B' are also independent. B) x = 1. No, for x = 1, A' and B' are not independent. C) x = 5. Yes, for x = 5, A' and B' are also independent. D) x = 5. No, for x = 5, A' and B' are not independent. E) There is no value of x for which A and B are independent.

A marathon is a long-distance race with an official distance of 26.2 miles (42.195 kilometers) and today there are more than 800 marathons held annually throughout the world. The Boston Marathon became the first major marathon to include a wheelchair division competition. This happened in 1975. One might wonder how male Boston Marathon winning finish times compare with the average male Boston Wheelchair Marathon winning finish time of 98.3 minutes. Let's test whether male Boston Marathon winners, on average, take longer to finish than male Boston Wheelchair Marathon winners by performing a one-sample t-test. We'll use a significance level of ? = 0.05.
