A Gallup poll asked a sample of Canadian adults if they thoughtthe law should allow doctors to end the life of a patient who is ingreat pain and near death if the patient makes a request inwriting. The poll included 295 people in Quebec, 230 of whom agreedthat doctor-assisted suicide should be allowed.
(a) What is the margin of error of the large-sample 99%confidence interval for the proportion of all Quebec adults whowould allow doctor-assisted suicide?
(b) How large a sample is needed to get a ±3 percentage pointmargin of error (this is very commonly used)?
Use the previous sample as a pilot study to get p*. (You mayneed four decimal places in your critical value to solve thisproblem.)
