About
This quiz focuses on sampling distributions and their properties, which is a fundamental topic in inferential statistics appropriate for Advanced Placement Statistics students in grades 11-12. The questions systematically assess students' understanding of key concepts including the distinction between parameters and statistics, the characteristics of sampling distributions (particularly for sample proportions and sample means), the Central Limit Theorem, and the properties of unbiased estimators. Students need to master the notation and vocabulary of statistics, understand that the mean of a sampling distribution equals the population parameter, calculate probabilities using the normal distribution when conditions are met, and recognize how sample size affects the variability of estimators. The mathematical complexity requires students to work with standard error formulas, apply z-score calculations, and interpret statistical symbols in context. These concepts build the foundation for hypothesis testing and confidence intervals that follow in the AP Statistics curriculum. Created by Angela Sage, a Mathematics teacher in US who teaches grade 9-12. This comprehensive review quiz serves as an excellent formative assessment tool to gauge student understanding before moving into Unit 6 of the AP Statistics course. Teachers can deploy this quiz as a warm-up activity to activate prior knowledge, assign it as homework to reinforce classroom instruction, or use it as a review session before summative assessments. The varied question formats help students practice the types of problems they will encounter on the AP exam while identifying areas that need additional instruction. This assessment aligns with Common Core Statistics and Probability standards S-IC.1 (understanding statistics as a process for making inferences about population parameters) and S-IC.4 (using data from sample surveys to estimate population means and proportions), as well as AP Statistics Learning Objectives related to sampling distributions and the Central Limit Theorem.

The Gallup Poll asked a random sample of 1785 adults whether they attended church during the past week. Let p-hat be the proportion of people in the sample who attended church. A newspaper report claims that 40% of all U.S. adults went to church last week. Suppose this claim is true.
What is the mean of the sampling distribution of p-hat?
