Gallup Poll Survey Analysis on Doctor-Assisted Suicide in Quebec

A Gallup Poll surveyed Canadian adults to find out their views on whether the law should permit doctors to end the life of a patient who is experiencing severe pain and is near death, given a written request by the patient. The study surveyed 264 individuals from Quebec, out of which 224 agreed that doctor-assisted suicide should be allowed.

Questions:

(a) What is the margin of error for a 95% confidence interval for the proportion of all Quebec adults who would agree with doctor-assisted suicide? Provide your answer to three decimal places.

(b) If the researchers aimed for a margin of error of 0.01 instead, what sample size would be necessary to achieve this?
