In this lesson, we learn how to estimate the mean weight of cereal boxes using a sample of 800 boxes. We are trying to estimate the mean weight of all cereal boxes in the population, but we don't know mu or the mean weight of the cereal boxes, and we don't know the standard deviation of the cereal boxes. However, we can use the central limit theorem to create a normal distribution called the sampling distribution, where the mean of all the x bars equals the mean of the population. We'll continue this problem in part two of the lesson.
