This lesson is the second part of estimating the population mean in statistics. The central limit theorem is applied to partition the sampling distribution of x-bars, with the result that it is 98% confident that the mean weight of all cereal boxes is between 31.73 and 31.77 ounces. The lesson shows how to calculate the confidence interval, and teaches how to write it in interval notation.
