Who It's For: Anyone looking for an introduction to statistical inference: moving from knowledge about a sample to knowledge about a population. Keep in mind this resource focuses on using the z-distribution for calculating confidence intervals for means (the t-distribution is covered in section 8.3 of this resource).

Why We Love It: This textbook chapter will help you understand how the 99, 95, and 90 percent confidence intervals you often see are calculated.
