A study оf heаlth cаre cоsts fоr coronаry angioplasty versus coronary bypass surgery at a London hospital showed an average cost of 6,176 pounds with a standard deviation of 329 pounds for 231 angioplasties and an average cost of 8,164 pounds with a standard deviation of 264 pounds for 221 bypass surgeries. Is this sufficient evidence to say that the average cost of angioplasty is less than the average cost of bypass surgery?
