AP Stats Exam 2018 FRQ #2: How do I Find How Many Students Recycle?

Welcome to our Hayes' World of Math! In this video, I talk through the solution for one of the free response questions from the 2018 AP Statistics exam - problem #2 that sees an environmental science teacher making a confidence interval for the proportion of students who recycle. The problem is from CED Unit 6 which covers inference for categorical data (proportions), estimating population proportions and difference of proportions, significance tests, and Type 1 & Type 2 errors. I will break down the problem step-by-step, providing clear explanations and strategies. Whether you're studying for the AP exam or just want to sharpen your statistics skills, you should find something helpful.
