Statistics 103.  Fall 2008.
Professor: Ethan Anderes.

PRACTICE PROBLEMS AND HOMEWORK.
Unless I explicitly say it, these problems are not to hand in. Only for practice. It is very important that you practice each week.  Don't fall behind!


Chapter 2:
All the problem in this chapter are good (including the discussion problem on page 18). Test your knowledge using the starred problem (2.6) on page 17. Make sure you can do these problems without referring to the formulas.

Chapter 3:
3.1-3.4.
               
Take a look at the following graphical displays of data and see if the use of area or volume is misleading (they may or may not be misleading): graph1, graph2, graph3, graph4.  Write up a short summary describing your conclusions.

3.7, 3.8, 3.10, 3.11, 3.15(a) and (c), 3.16.

Challenge yourself by doing 3.17 and 3.18 . (I mistakenly added 3.18...quiz 1 will not cover it.)

Discussion questions 1 and 2 are also challenging and good to discuss.

3.5-3.11.

3.13, 3.14.

3.17.

Discussion question 2.

Chapter 5:

It looks like all these problems are good. I recommend doing them all! The main challenge for these problems is setting up the problem correctly. If your having trouble, try setting up the problem different.

Note: 5.7 and 5.8 are hard so don't get discouraged.

Note: The starred problems 5.38-5.43 are hard. Indeed more difficult than the problems that will be on the midterm. Therefore, I wouldn't worry too much about these unless you really wanted to test yourself.

I've got some requests for some more straight forward problems with solutions. Here are some problems that I posted for another class. I think they are good practice for the midterm:
Extra Problems 1.
Solutions. 

Chapter 6:

6.1-6.4

6.6-6.11 (these are fundamental)

6.12-6.13 (these are bit harder. They require using both a binomial formula and some probability rules)

Note: I posted a homework assignment to be handed in under the links section of the main course web page.
