These are the goals for week 3

The Book

We will cover the material in chapter 7 sections 2-4 and begin a discussion on chapter 8.1. Chapter 7 deals with confidence intervals. This is where we use the data, and some assumptions about the parent distribution to guess at values of the parameters.

In chapter 8 we learn hypothesis testing. In brief, you hypothesize that you know the values of the parameters, and from this compute the probability of the data you have. Based on the $p$-value you decide if you wish to accept or reject your hypotheses.

Minitab

We will learn about the $t$-distribution, how to use MINITAB to do 1-sample $z$, 1-sample $t$ tests and the sign test for the median.

Newspaper assignment

For Wednesday, please bring in some article from the paper where bivariate data is discussed. This can be a graphic or an article. Be prepared to discuss it with the class using any appropriate terminolgy for 2-3 minutes.
