Practice Questions For Exam 2

* This is a set of slides with a bunch of "fill in the blank" questions about statistical inference, confidence intervals, and hypothesis tests
* My answers to the questions are revealed as you advance the slides
* Try to answer each one on your own first, then check your answer against mine
* There are multiple correct ways to word many of the answers
