STAT 245 Study Guide - Peripheral Neuropathy, Confidence Interval, Hyperglycemia
Document Summary
Review questions 3 for final exam - solutions: peripheral neuropathy is a complication of uncontrolled diabetes. The number of cases of peripheral neuropathy among a control group of 350 diabetic patients was: among a group of 115 patients who were taking an oral agent to prevent hyperglycemia, there were 35 cases of peripheral neuropathy. For the group taking an oral agent p = We will reject h0: p1 = p2 in favour of ha: p1 p2 if z < -z0. 025 (-1. 960) or z < z0. 025 (1. 960). z. Construct 95% confidence intervals for the proportion of patients with peripheral neuropathy in the medication group and the proportion of patients in the control group. Construct a 95% and a 99% confidence intervals for difference in the proportion of patients with peripheral neuropathy between the medicated group and the control group. Solution: (1 a )% confidence limits for a difference in proportions p.
