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 255 people in Quebec, 203 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) (Answer = .049)

(b) Suppose the researchers wanted a margin of error of 0.01 instead. How large a sample would be needed to achieve this? Use the previous sample as a pilot study to get a value for p^.(The Answer is NOT 9604)
