Chapter 7: Confidence Intervals

Chapter 7: Confidence Intervals. The Review. Basic Idea. Instead of giving a point estimate for the parameter we are trying to estimate, we provide a range of values wherein the true value of the parameter is contained. This range of values is what we call confidence interval.
