Answer 40 questions in 15 minutes.
If you are not ready to take this test, you can
study here
.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it reenforces your understanding as you take the test each time.
1. Type I vs Type II error (including how you decrease the probability of getting them)
2. Where does most abnl actions in sleep occur?
Risk without tx minus risk with tx
