This study guide covers confidence intervals for regression slopes in AP Statistics. It reviews regression basics (point estimate, interval estimate), explains confidence levels, and how to interpret confidence intervals (including width and what it means if zero is in the interval). It also provides an example of analyzing computer output to calculate and interpret confidence intervals, and practice questions including multiple-choice and free-response with scoring breakdowns.
