Please complete the Chapter 12 Quiz A/C worksheet provided in class. I know we haven't formally named all of these sample types and biases in class, but you should use your notes (from reading the chapter) to help you figure this out. We'll allude to this homework as we push to finish up chapter 12 by Wednesday.
(Our goal is to test on this unit by Christmas break).
Also, the crossword puzzle is an extra credit homework assignment.
We also have a quiz Monday on linear regression. Be sure you can:
1. Interpret slope
2. Interpret y-intercept
3. Interpret the coefficient of determination (R^2)
4. Find correlation given R^2.
5. Calculate a residual (first generate a predicted value with the equation, then find a residual)>
Finally, you all should be working on corrections to make up your test. I will be after school Monday for those who need help with some of the problems.
Enjoy the weekend and I look forward to seeing you all Monday!

Tuesday HW
One last shot at simulations...
Please complete the following...
Page 266: 1,5,6,33,35...........................37,38
To Make Up The Test...
1. For each incorrect response, identify why your answer is incorrect; what mistake did you make?
2. Then, explain why the correct answer is correct (in detail!)
*All complete sentences
*All in context (no A,B,C,D...)
*If you do this successfully you earn a "check" and then are allowed to re-take the test after school, during lunch, or during study hall.

Monday HW
Tonight please complete the 2 simulation problems--Chapter 11 Quiz B and the AP problem from the 1998 exam.
We'll discuss both of these in class tomorrow; then we'll move onto some discussion of our multiple choice test! Yay!

Tuesday HW
Yeah, that's right. I did it. Homework the night before pep rally.
(It's short).
Write a procedure to simulate this scenario. Then, conduct 5 trials and record/interpret your results.
57 students participated in a lottery for a particularly desirable dorm room—a triple with a fireplace and private bath in the tower. Twenty of the participants were members of the same varsity team. When all three winners were members of the team, the other students cried foul. Use a simulation to determine whether an all-team outcome could reasonably be expected to happen if everyone had a fair shot at the room.
**And don't forget about your crossword puzzle. I still can't figure out 3 down; don't worry if you're missing 1 or 2 or 3. But not 4. Then worry.**
