A Study Of Health Care Costs For Coronary Angioplasty Versus Coronary Bypass Surgery At A London Hospital Showed An Aver 1 (19.91 KiB) Viewed 18 times

A study of health care costs for coronary 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? p<.001" so this is very strong evidence that angioplasty costs less. O'p is between .001 and .01 so this is strong evidence that angioplasty costs less. 'p is between .01 and .05 so this is moderate evidence that angioplasty costs less. 'p is between .05 and .1 so there is some evidence that angioplasty costs less. p>10 so there is little evidence that angioplasty costs less.
