A 2011 poll in Canada indicated that 41% of Canadians favored bringing back the death penalty for convicted murderers. (The United States is the only Western democracy that has it.) A report by Amnesty International on this and related polls (www.amnesty.ca)

did not report the sample size but stated, ‘‘Polls of this size are considered to be accurate within 2.5 percentage points 95% of the time.’’ If this is the case, about how large was the sample size?
