3. Homer surveys a random sample of 50 Canadians on the size of government. Specifically, he asks if they prefer a much smaller government (1) or a much larger government (10). His sample, which is normally distributed, has a mean of 6.2 and a standard deviation of 2.5. Define the confidence interval (1 point). Can we say Canadians at the population level have a clear opinion on this question (1 point)?
