A stent is a wire mesh tube that is placed in a blood vessel to keep it open. A total of 1120 patients received a new kind of stent that was coated with a drug designed to prevent a blockage in the blood vessel. Of these, 134 required additional treatments within a year. Can you conclude that less than 15% of patients receiving these stents require additional treatment? Use the a=0.05 level of significance.
