AP Statistics Assignment for 3/29

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).

We did some more work with understanding the nature of mathematical independence today, including making some graphs to help illustrate whether or not independence exists in a group of data.

You knew this was coming! Tonight, please complete the Chapter 24 Investigative Task – SAT Part II. Use the same sample you selected for the previous task (though here’s the sampling frame again if you need to gather a new sample) and submit your response to me by the start of class tomorrow.

As usual, your response should be completed in a Google Document and submitted to me (bkirk@icsd.k12.ny.us). Please name your file appropriately.  The file name should have the format “LastName.FirstName.Ch24InvTask”. For example, mine would be “Kirk.Benjamin.Ch24InvTask”.

Finally, it’s getting to be about time where we will start reviewing for the AP exam. We will be using the 9th edition of Barron’s AP Statistics review book to aid our review process. Please purchase a copy of this book by Friday, April 5th. By Friday, either bring in your book or take a selfie of you holding it with your name clearly written across the front. Every student must have their own copy of this book, that you can write in and mark up as we go through our review. If you are concerned about obtaining your own copy (for whatever reason), please contact me ASAP and we’ll work out an arrangement.

Today we discussed an important idea in probability and statistics: determining when events are independent and/or mutually exclusive.

You met with a group of peers in class today to look at a set of review problems from both Unit 5 and Unit 6. Your assignment tonight is to complete the inference procedure suggested by each question. You must do each question your group assigned to you in its entirety on separate pieces of paper. When we get back to class tomorrow, you’ll have time to check in with your group before stacking the problem sheets, stapling them together, and turning them in to me.

If you weren’t in class today, then pick any three of the problems in the file linked above, complete your response, and turn them in.

Intermediate Algebra Assignment for 3/26

We did some more work with the counting principle today, using it in a variety of applications. The trick is to carefully sort out the number of choices you have to make and the number of options you have for each choice.

We started our second-to-last unit today, about tools of probability. Probability is all about chances and odds, determining how likely various events are to occur. We’ve started with some very basic ideas of probability, but we will quickly move to some more complicated and nuanced applications.

Your Unit 7 test is tomorrow. Take some time to review!

AP Statistics Assignment for 5/21

In class today, we’ll be doing an activity that involves using data from this Major League Baseball SRS tool.

Tonight, complete the Chapter 22 Investigative Task. You’ll need to select your sample from the sampling frame found here. This will be due at the start of class tomorrow, and as usual, your response should be completed in a Google Document and submitted to me (bkirk@icsd.k12.ny.us). Please name your file appropriately.  The file name should have the format “LastName.FirstName.Ch22InvTask”. For example, mine would be “Kirk.Benjamin.Ch22InvTask”.

I recommend using Stapplet for any graphing needs you may have and EquatIO for writing your equations (see this document for tips and examples).

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 did some more work with the Law of Cosines today, specifically looking at two cases where it is useful: when given two sides and a single angle between them (SAS) and when given three sides but no angles at all (SSS). Note that this second case is exactly what your poster will feature!

Intermediate Algebra Assignment for 3/13

As we’ve observed in class, in order to use the Law of Sines, you must know (or be able to find easily) an opposite angle-side pair in the triangle. But what if all you have is two sides and an angle? Is there anything we can do with that? Enter the Law of Cosines, a generalization of the Pythagorean Theorem to non-right triangles.

Also, don’t forget about your poster project, due next Tuesday!
