Confidence Intervals with Proportions Unit

This unit introduces the topic of a sampling distribution. We discuss the properties of sampling distributions and how the sample size will affect the shape and variation of the distribution, as well as how that would then affect calculated probabilities within that distribution. Examples of how to calculate those probabilities from tables and also using technology are shown. The unit then introduces the concept of a confidence interval. The assumptions needed to conduct such an inference procedure are formalized as are the calculations and formal written conclusion. The unit concludes with a discussion of how to calculate sample size given a confidence level and margin of error, as well as discussing the difference between interpreting a confidence level and a confidence interval.

Included a unit outline, a powerpoint to deliver all content, 5 practice worksheets, 2 reviews, an AP Style FRQ (for quiz or extra practice) and a test bank.
