Sections 01, 02 and 03, Spring 2003.

Old Exams that might be useful in stuying for the final.

The assignments below are your best guide to what will be covered on your final. These old exams overlap that material. They may contain some topics we did not cover this semester and there may be topics we did cover that are not on these exams. One thing that is missing is any graphical handouts -- figures, illustrations, graph paper, etc. Also, all exponents are messed up. If you study first and then try to work one of the old exams it will give you some feedback as to how much of the material you know. Trying to just learn the test items that appeared on these old exams will probably not lead to a very good score on your final.

One version of this semester's EXAM I can be found here.

Another version of this semester's EXAM I can be found here.

Section 08, EXAM 1C, Fall 2002   covers a different selection of topics than the exams above.

An old EXAM II   covers topics from Chapters 4, 5 and 7.

All the old exams include answers but not the steps in the calculations.

EXAM III is on 1 May.

EXAM III covers Sections 8A, 8B and all of Chapter 5. You should bring a ruler and a calculator. No notecards are allowed for EXAM III. You may bring one notecard to the final.

Assignments

Due 29 April

Read 8B and do Exercises 1, 3, 5, and 9 through 20.

Due 24 April

Read 5D and do Exercises 1 and 17. Also make a stem and leaf plot for every column of figures on the back of the Rainy Day Answers class handout from the 15th.

You can find solutions to the above here.

Due 22 April

Read 5C and do Exercises 1-7, 9 (skip "cumulative"), 15, 19.

Read 5E and do Exercises 5, 7, 13 and make scatter plots of the data sets on the back of the Rainy Day Answers class handout from the 15th.

Bring all your scatter plots to class.

Bring your textbook to class.

Scatterplots of the data on the handout can be found here.

Due 17 April

In class on 15 April I showed people how to make stem and leaf plots. This material is not in your textbook, so if you missed this class you should print out all the info on this site on this topic and go to the Math Activity Center on the third floor of Hyde for help. This is a standard Stats.I topic so anyone in the MAC should be able to help you.

The first example on making stem and leaf plots that I did in class on 15 April is available as a PDF file. (The first page of this document was a class handout on the 15th. All of the stem and leaf plots there were made by Minitab, which always sorts the leaves, and also inserts an extra column of numbers at the left which you may ignore.) You will need Acrobat Reader to open this file. It is already installed on all college computers. (If you don't have Acrobat reader on your own computer, you can download it for free from the Adobe web site.)

You can also view the second and third examples. Due to time running out, the third example was covered briefly or not at all in class. The link above takes you to a detailed analysis.

Stem and Leaf Homework

Finish the stem and leaf of the rainfall data that was started in class. (Answer is the third stem and leaf in the document cited above. All of the stem and leaf plots there were made by Minitab, which always sorts the leaves, and also inserts an extra column of numbers at the left which you may ignore.)

Find the mean of the rainfall data.

Find the mean for the family size data on the back of the Rainy Day Answers handout distributed in class. (This data can also be found on p.260 of your textbook.)

For the following data sets:

do the following
  1. Make a stem and leaf without splitting stems.
  2. Make a stem and leaf but split the stems.
  3. Describe the shape of the data distribution and note any possible outliers.
  4. Find the mean, mode (if any), and median of the data. Which of these three would make a reasonable "typical value" for this data set?
You can find solutions to the above here.

For the following data sets:

do the following
  1. Make a stem and leaf on an appropriate scale.
  2. Describe the shape of the data distribution and note any possible outliers.
  3. Find the mean, mode (if any), and median of the data. Which of these three would make a reasonable "typical value" for this data set?

EXAM II was on 3 April.

EXAM II covered Sections 3C, 4A, and all of Chapter 7. Students were allowed to bring to the exam a 3 inch by 5 inch notecard on which they could write anything they wanted (on both sides and all four edges) and could also bring a ruler and a calculator.

Due 1 April

Read 7C except for the sections involving logarithms, which are:

We finished the example on p.381 in class on 27 March without using logarithms. If you missed that class you should get notes from someone who was there or read ALL of 7B and 7C and use logarithms.

Do Exercises 7 and 11 (carry both out to two doubling times), 15, 17, 19, 21, 23.

Due 27 March

Read 7B to the bottom of p.365 (skip the material on logarithms) and do Exercises 5, 7, 9, 15, 17, 19, 21, 23, 25, 31, 33.

Due 25 March

Read 7A and do Exercises 1, 3, 5, 7, 9, 13, 15, 17. For all instances of exponential growth, find the doubling time (or half-life) and extend your table until the value is doubled (or halved).

Due 13 March

We will have a quiz on interest (Section 4A) and go over EXAM I. You can get versions of the exam that have the same questions (with answers) as the afternoon or evening exams, but with the questions sorted in the order the material appears in the text. Please print out the version for your section so we can be working from the same test in class.

Due 11 March

Make a table for problem 3 in 4A (p.191) that goes out 20 years. On a single piece of graph paper, graph the amount each person has over this time period. Turn your graph in.
