olo Treating circulatory disease: Angioplasty is a medical procedure in which an obstructed blood vessel is widened. In some cases, a wire mesh tube, called a stent, is placed in the vessel to help it remain open. A study was conducted to compare the effectiveness of a bare metal stent with one that has been coated with a drug designed to prevent reblocking of the vessel. A total of 5314 patients received bare metal stents, and of these, 832 needed treatment for reblocking within a year. A total of 1119 received drug-coated stents, and 140 of them required treatment within a year. Can you conclude that the proportion of patients who needed retreatment is less for those who received drug-coated stents? Let p, denote the proportion of patients with bare metal stents who needed retreatment and p, denote the proportion of patients with drug-coated stents who needed retreatment. Use the a = 0.05 level of significance and the P-value method with the TI-84 Plus calculator. Part: 0 / 4 Part 1 of 4 State the appropriate null and alternate hypotheses. Ho: H1: This hypothesis test is a (Choose one) v test.

Can you conclude that the proportion of patients who needed retreatment differs between those who received bare metal stents and those who received drug-coated stents? Let p1 denote the proportion of patients with bare metal stents who needed retreatment and p2 denote the proportion of patients with drug-coated stents who needed retreatment.
