... The poll produces a single estimate for the public’s thinking, but this estimate is a range of possible estimates. The sampling error is about four percent for a sample of six hundred respondents. That four percent generates the confidence interval. With that said, caution is always required when in ...

... The point estimate, x-bar, must be calculated from an SRS for the results to generalize. Outliers can have a big effect on confidence intervals. Check for these graphically. When the population is non-normal, the Central Limit Theorem is important (n ≥ 30). You must know σ from the population. ...
