Class Notes 3-30

In class today the students got back their confidence interval and hypothesis testing quizzes. We then started our coverage on Inference of Means (chapter 23).

We then worked on some problems from the book.

Today in class we took our Confidence Interval and Hypothesis Testing Quiz.

Homework: Read Chapter 22.

Class Notes 3/22

The first portion of today's class was focused on attempting an AP free response question in a timed fashion and then going over that question.

We then finished our chapter 21 notes on hypothesis testing wisdom. We talked about the Power of a hypothesis test and how reducing a Type I error increases a Type II error as well as the other way around. We also discussed that in order to decrease both a Type I and Type II error is to increase the sample size.

The students then worked on a few questions from the book.

Homework due Friday 3/24: Read Chapter 22.

Class Notes 3/1

Today the class worked on an AP free response question, we then looked at the correct answers and looked at some actual student work and looked at how answers are graded. We then went over the homework that was due for class and then worked in groups on more examples from the book on the Central Limit Theorem.

Homework due Friday 3/3: PG. 432 #1-19 odd.
