Inference: Errors & Power of Tests
Join us to learn about Inference understand errors and the power of tests.
Review of Inference: z and t Procedures
We review how to construct confidence intervals and run hypothesis tests for proportions (z-procedures) and means (t-procedures). We also practice choosing the appropriate procedure for different situations.
Inference: Hypothesis Tests for Means
We review the general process for conducting hypothesis tests on the AP Exam, then conduct 1-sample t-tests, 2-sample t-tests, and matched-pairs t-tests. We then compare and contrast t-tests to z-tests
Inference: Confidence Intervals for Means
Construct and interpret 1 and 2-sample t-intervals for population means (or difference of means).
