- 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 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. Use the α=0.10 level of significance and the P-value method with the TI-84 Plus calculator. a)State…Angioplasty is a medical procedure in which an obstructed blood vessel is widened.

Researchers want to determine whether or not higher folate intake is associated with a lower risk of hypertension (high blood pressure) in women (927 to 44 years of age). To make this determination, they look at 7373 cases of hypertension in these women and find that those consume at least 1000 micrograms per day of total folate had a decreased risk of hypertension compared with those who consume less than 200 A: B:Erythropoietin (EPO) is a banned drug used by athletes to increase the oxygen-carrying capacity of their blood. New tests for EPO were first introduced prior to the 2000 Olympic Games held in Sydney, Australia. Chance (Spring 2004) reported that of a sample of 830 world-class athletes, 159 did not compete in the 1999 World Championships (a year prior to the new EPO test). Similarly, 133 of 825 potential athletes did not compete in the 2000 Olympic Games. Use a 90% confidence interval to compare the two proportions. Was the new test effective in deterring an athlete’s participation in the 2000 Olympics? Use the CI information to make your conclusion
- Vertical banded gastroplasty is a surgical procedure that reduces the volume of the stomach in order to produce weight loss. In a recent study, 82 patients with Type 2 diabetes underwent this procedure, and 59 of them experienced a recovery from diabetes. Does this study provide convincing evidence that more than 60% of those with diabetes who undergo this surgery will recover from diabetes? Use a 5% level significance.Erythropoietin (EPO) is a banned drug used by athletes to increase the oxygen-carrying capacity of their blood.

There are several possible mutations of different degrees of importance but the disease expresses itself only when at least 2 arepresent in any one individual. A blood analysis was performed on 3,000 blood samples from newborn babies of Caucasian descent in the state of Michigan, USA. The results showed that 163 of those sampled carried two mutations in the HFE gene. a. What is the proportion in the sample that carry the two mutations of the HFE gene? b. Calculate the 95% confidence interval for the proportion of this population that carries two mutations in the HFE Check the data for the necessary conditions and show full working. c.

- Identify the (a)population and (b) sample in the study. A quality-control manager randomly selects 70 bottles of ketchup that were filled on July 17 to assess the calibration of the filling machine. Researchers want to determine whether or not higher folate intake is associated with a lower risk of hypertension (high blood pressure) in women (27 to 44 years of age). To make this determination, they look at 7373 cases of hypertension in these women and find that those who consume at least 1000 micrograms per day (µg/d) of total folate had a decreased risk of hypertension compared with those who consume less than 200 µg/d.Women athletes at a certain university have a long-term graduation rate of 67%.
