Two surgical procedures are widely used to treat a certain type of cancer. To compare the success rates of the
two procedures, random samples of the two types of surgical patients were obtained and the numbers of
patients who showed recurrence (happened again) of the disease after a 1-year period were recorded. The
researcher is wondering if there is sufficient evidence to conclude that procedure A is better than procedure B.
Assume all assumptions and checks have been met and verified.
