These are the notes for 2-sample means intervals/tests (from class on Tu/W, Feb 25/26):

• Ch 24 SLIDES | EXAMPLE PROBLEMS

This worksheet goes with the bookwork for HW #15:

• 23 Worksheet - What Sample Size is Needed

This worksheet (obtaining p-values from simulations) is due the class AFTER the Ch 20-22 test.

It will count as the first grade of the 5th Six Weeks, and will be a non-droppable grade.

• 20 Worksheet - Simulations Pig Dice Naptime

Here is the test review for the big exam on W/M, Feb 12/17 (update: test postponed to F/Tu, Feb 14/18). Partly because of all of the weather-related issues, I am also posting FULL solutions.

• Review Chapter 20 - 22 | ANSWERS ONLY | FULL SOLUTIONS

Since A-day will not take the quiz until later in the week, I decided to count as a homework grade (and not a quiz grade).

As a trade-off, last week's pink HW quiz (over 1-proportion z-tests) will count as a quiz grade.

Even though we only have two quiz grades for the six weeks, we will still drop one.

If you are in 7th or 8th period, the test is tomorrow (Weds, Feb 12).
