12) In a random sample of 50 patients undergoing a standard surgical procedure, 15 required medication for postoperative pain. In a random sample of 90 patients undergoing a new procedure, only 16 required pain medication. A physician claims that the proportion of patients who need pain medication is the same for both procedures. Test the claim with an appropriate hypotheses test. Use a 0.05 level of significance. a) Define the parameter(s).
