A Gallup Poll asked a sample of Canadian adults if they thought the law should allow doctors to end the life of a patient who is in great pain and near death if the patient makes a request in writing. The poll included 264 people in Quebec, 224 of whom agreed that doctor-assisted suicide should be allowed. (a) What is the margin of error for a 95% confidence interval for the proportion of all Quebec adults who would allow doctor-assisted suicide? Use 3 decimal places. type your answer... (b) Suppose the researchers wanted a margin of error of 0.01 instead. How large a sample would be needed to achieve this? type your answer... Suppose that a committee is studying whether or not there is waste of time in our judicial system. It is interested in the mean amount of time individuals waste at the courthouse waiting to be called for jury duty. The committee randomly surveyed 81 people who recently served as jurors. The sample mean wait time was 8 hours with a sample standard deviation of 4.6 hours. Construct a 95% confidence interval for the population mean time wasted. State the confidence interval. Use 3 decimal places. type your answer... type your answer...
