Test 2 will be on Tuesday, 2 March 2010 and will cover the topics covered from Chapters 1, 2, 3, and 4.

Today, we covered most of Chapter 4. The only remaining concept from this chapter is using the least-squares regression line to predict values for the response variable – we’ll discuss this on Thursday. Remember that all calculations are done using the TI83/84:

Section 4.1: How to make a scatterplot

Section 4.2: How to calculate the correlation coefficient, r

Section 4.2: How to find the least squares regression line

The applet that we used in class to compare scatterplots with the Pearson correlation coefficient is located at: http://www.stat.uiuc.edu/~stat100/java/GCApplet/GCAppletFrame.html.

You should be able to complete the following assignments in Chapter 4 (except for predictions which will be covered in the next class):

Section 4.1: #1-9 odd, 11-16, 19-31 odd;

Section 4.2: #9, 17-21;

Section 4.3: #1-11 odd.

Remember, you are required to submit the following only on Tuesday (don’t forget about the assignment listed in previous post!):

Section 4.1: #23, 27;

Section 4.2: #17, 21;

Section 4.3: #5.
