AP Stat – HW #4 (due Weds, March 2)

Monday, February 28, 2011 10:30 AM AP StatisticsMister Youn

Today we went over Chapter 25 – paired t-tests and intervals. These are special procedures for inference to compare means of two groups that are NOT independent of one another. We also took a short quiz over Chapter 23 (one sample t-procedures).

Here are both the notes from class (if the ppt doesn’t work, then try the PDF version) and the homework assignment due on Wednesday:

Ch 25 Paired Means.ppt | PDF Version
Homework: Chapter 25, #1, 4, 5, 11, 14, 20

Coming up in the next week:

Group Quiz through Chapter 25: This Friday (March 4)
Major Test through Chapter 25: Tuesday, March 8

Don’t forget to sign up for the math relay (March 9), worth 5 bonus points on the test!

The first major test of the 5th six weeks is coming up in less than a week~

As it says on the review, please do problems 1-5 without using a calculator.

AP Stat – HW #3 (due Monday, Feb. 28)

Today we went through chapter 24 (inference with 2-sample means). If you are doing the reading on your own, be advised that we are NOT using pooled procedures for means, so skip that part from the reading.

Homework is:

Ch 24 p.566, #2, 5, 6, 7, 10b, 17, 24, 30, 34 (sparrow and robin ONLY)
Worksheet: Ch 23 What Sample Size is Needed.pdf (instructions at the top should be self-explanatory)

AP Stat – HW #1 (5th Six Weeks, due Tuesday, Feb. 22)

A couple of items…

Both sides of this worksheet given out after the test in class: 2009B #1 and #4.pdf
Go back to Chapter 18, and work #25, parts (c) and (d). We are about to get into inference with means, so work this problem that deals with sampling distributions of means.
READ pp 520-523 (the first 4 pages of Chapter 23)

Be advised that we are moving quickly this next week, so if you plan on missing class, try to get a classmate to take good notes for you (or read the book?). By the end of next week, we will be through Chapter 24.
