Choose the statement that is FALSE. When sampling for means and thinking about the Central Limit Theorem, the n should always be >30. Reducing the variation of a process will increase the width of a given Confidence Interval relative to that process. When estimating the standard deviation in calculating confidence intervals, make sure you use the t tables. A 95% confidence interval is wider than a 90% confidence interval
