Your Unit 6 test is tomorrow. Remember that while the focus of the test will be on content from Unit 6, it will include content from Unit 5 also. So while the only tests/confidence intervals I’ll ask you to calculate will be t-tests, you should still expect to possibly see questions about z-tests, power, Type I/II errors, etc.
I gave you Unit 6 Test Review Materials in class today. There are some extra practice problems in there that would be good to look at.
