Monitor the room to support student learning. As each pair finishes, send them to the white board to write up 1 of the steps STATE, PLAN, DO, or CONCLUDE. The first two pairs should handle the PLAN and the DO because they take the longest to write up.Use = .05. b) Explain why the design of this experiment is better than having two separate treatment groups with one group of students measured while sitting and the other group measured while standing.

Chapter 9 of the AP Statistics curriculum covers the topic of hypothesis testing, including null and alternative hypotheses, significance levels, p-values, and interpreting test results.

Ask them if they are more likely to find statistically significant results if they have an alternative mean of 1 or 1000. They will of course say 1000. Explain how power is a probability of finding statistically ...the probability that we obtain the statistic in repeated random samples. the mechanism that determines whether randomization was effective. the distribution of values taken by a statistic in all possible samples of the same size from the same population. the extent to which the sample results differ systematically from the truth.
Now, about the activity. Students should work in groups (or pairs) on page 1. By the end of the page, they will write a formula for a z-score. For now, we prefer to use words rather than symbols: z-score = (value – mean) / SD. We don’t want students to have to wrestle with mu vs xbar and sigma vs s. We will save that discussion for Chapter 7.Chapter 9 Summary and Cheat Sheet. Most real-world statistical problems involve trying to use sample statistics to make inferences about unknown parameters. This chapter is a prelude, in which we describe the distribution of a sample mean when the population mean and standard deviation are known parameters.
