STATISTICS Two Proportions

Answer the given problem. Analyze what tool should be used. In a Kidney International article, Avram et al. reported on a study involving 529 hemodialysis and 326 peritoneal dialysis patients. They found that at baseline 249 subjects in the hemodialysis treatment group were diabetic, while at baseline 134 of the subjects in the peritoneal dialysis group were diabetic. Is there a significant difference in diabetes prevalence at baseline between the two groups of this study? Let = 0.05. What does your finding regarding sample significance imply about the populations of subjects? These are the steps to solve the problem: 1. Hypothesis ex. H0: = 9.0 H1: 9.0 2. Level of significance ex. = 0.01 3. Test Statistic ex. z = x - 0 / / n 4. Critical Region ex. graph and /2 = +-0.025 5. Computation ex. compute using formula 6. Decision ex. accept H0 since the computed z-value falls in the region of acceptance. 7. Conclusion ex. there is no reason to believe the ...
