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 remaln 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 5329 patients received bare metal stents, and of these, 830 needed treatment for reblocking within a year. A total of 1125 received drug-coated stents, and 146 of them required treatment within a year. 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 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= 0.01 level of significance and the P-value method with the TI-84 Plus calculator. Part 1 of 4 State the appropriate null and alternate hypotheses. Ho P1 = P2 H P * P2 v test. This hypothesis test is a two-tailed Part: 1/4 Part 2 of 4 Find the P-value. Round the answer to at least four decimal places. P-value =

Transcribed Image Text: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 5329 patients received bare metal stents, and of these, 830 needed treatment for reblocking within a year. A total of 1125
received drug-coated stents, and 146 of them required treatment within a year. 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 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 = 0.01 level of significance and the P-value method with the TI-84 Plus
calculator.
