What you’ll learn to do: understand the relationship between sample mean and error bound and confidence intervals

Successfully completing college may partly depend on attending class. A college retention office wants to know the average number of classes missed by students in a semester. Even if they find the sample mean to be 5 classes, it is unlikely that the true population mean number of classes missed is 5. To give them a better idea of what the true mean number of classes missed is, a confidence interval of values is created. In this section, you will learn the steps to forming and interpreting confidence intervals for a single population mean.
