Our Unit 6 test will be on Monday, April 1st (sorry, no April Fools Day joke here).
You got a batch of Unit 6 Review Materials in class today, which has answers to selected textbook questions. Naturally, you should do those before you examine the textbook solutions. Specifically: read the overview of the unit on pages 657-658, then work on exercises 7, 8, 9, 31, 34 from pages 659-665. In addition, read the scenarios described in questions 10, 15, 32, 36, and 42 and identify the procedure you would use to answer each question (and feel free to do them, but I don’t expect you to).
This is a Unit 6 test, so the only procedures I’ll ask you to actually do will be t-tests and intervals from Unit 6. You will however be asked to identify when you might use any of the procedures you’ve learned so far (z or t).
Our test on Unit 7 will be on Friday, March 22, so we’ll spend tomorrow and Thursday reviewing the Law of Sines, Law of Cosines, and related information ahead of this test.
Tonight, please finish HW 7.10.
We will have our Unit 5 test on Wednesday, March 13. Monday and Tuesday we’ll spend some time reviewing.
In preparation, please work on some of the review from the end of the unit. Read the unit summary on page 562, then on pages 562-568 do exercises 5, 6, 11, 12, 18, 30, 31, 37.
We will have a test on chapters 17-19 later this week (currently, it is scheduled for Wednesday, February 27). In preparation, I’ve selected some questions from each chapter. Your homework is to do at least one exercise from each chapter. I’ll provide you with solutions to all of them.
- From chapter 17 (pages 468-471): 23, 25, 53
- From chapter 18 (pages 491-492): 22, 34, 36
- From chapter 19 (pages 514-515): 22, 24, 33
I invite you to try all of these problems!
The applet for today’s activity can be found here. Using this simulator, find:
- Two very different values of p and n that create a distribution that you would confidently identify as “normal”
- Two very different values of p and n that create a distribution that you would confidently identify as “not normal”
- At least one value of p and n that creates a distribution that might be normal, but you’re on the fence about.
Report your findings here
For homework this weekend/next week, please finish reading Chapter 16, pages 423-429, then work on exercises 32, 33, and 34 from page 432.
Out Unit 4 Test will be on Wednesday, January 30. We’ll spend Monday and Tuesday after we get back from midterm exams reviewing the unit. Over next week, I recommend you work on the following practice problems from the Unit 4 review, pages 434-439: 5, 16, 20, 21, 23, 25, 27, 28, 37.
Due to today’s 2-hour delay, we will have the in-class Chapter 12 Investigative Task tomorrow, Thursday. It will still be closed-notes/closed-book. The schedule in the mid-year project folder has been updated.
Today you finalized your idea and started work on your project proposal. This proposal is due on Friday at the start of class, so you will need to collaborate on this outside of class.
On Friday we will review for our Unit 3 test, to be held on Monday, December 3rd. By then, you should complete the textbook review assignment: pages 331-336, exercises 1, 3, 7, 9, 11, 15, 19, 20, 23, 29, 32, 40, 41
Finish up Chapter 12 by reading pages 319-325 and doing exercises 32, 33, 39 from pages 327-329. Also please finish the Chubby Dogs Experiment example we started in class.
Upcoming Items of Note
- Tomorrow, we’ll introduce the mid-year project. You’ll be forming project groups and brainstorming ideas initially, and will finalize your idea and submit a project proposal by Friday. If you want to preview the details of the project, you can find information here.
- Wednesday, we’ll have an in-class Investigative Task for Chapter 12. This will be a closed-notes, closed-book task!
- Next Monday will be our test on Unit 3. After you submit your project proposals, we’ll spend the rest of Friday reviewing. I would suggest you get started on the review assignment (will not be checked for homework, so don’t stress!): pages 331-336, exercises 1, 3, 7, 9, 11, 15, 19, 20, 23, 29, 32, 40, 41
