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

5. How heavy are the backpacks carried by college students? To estimate the weight of backpacks carried by college students, a researcher weighs the backpacks from a random sample of 58 college students.
