Math 2200 Syllabus

This course is an elementary introduction to probability and statistics. We will study discrete and continuous random variables, mean and variance, hypothesis testing, confidence limits, nonparametric methods, Student´s t distribution, analysis of variance (ANOVA), (multiple) regression, and contingency tables. A graphing calculator with statistical distribution functions (such as the TI-83 series) is required.

Students considering a major or minor in mathematics should take Math 3200, NOT Math 2200. The prerequisite for this course is Math 131 or equivalent.

Textbook

DeVeaux, Velleman, and Bock - Stats: Data and Models (3rd edition)

Computing

A graphing calculator is required. Examples: Texas Instruments calculators TI-83, TI-84 or TI-89.

Homework

Homework will consist of problems from the textbook that will be given at the end of each class. Usually six problems will be given for each chapter. Two of these will be worked out in class, two others shall be odd-numbered with answers at the back of the book. You should work out these problems and check them with the solutions provided. That leaves you with two problems whose answers you do not know.

Homework will not be collected or graded, but at least 60% of the exam problems will be based on your homework assignments. If you should wish your homework to be corrected/commented then please submit your answer-sheets to me after the lecture.

Exams and Grading

There will be three in-class regular exams and an in-class final exam. The exams will have 20 multiple-choice questions. At least sixty percent of the exam questions will be based on your homework problems.

During Exams

You should bring several pencils with erasers. Do not bring any "scratch paper." There should be enough space for your work on the exam booklet.

You should also bring a TI-83, 84 or 89 series scientific calculator with you.

You may bring a single 3x5 note card with any notes (on both sides) that you like.

Exam Absences

You are expected to attend all exams at their scheduled time. Excused absences may be granted in case of severe illness, bereavement or other extraordinary circumstances. Approval for absences must be obtained in advance.

An unexcused absence from any exam receives a score of 0.

Grading

Your course grades will be based on the 4 exams. Each exam will be worth 25% of your grade. However, I will also calculate a score where each of the three regular exams will be worth 20% of your grade and the final will be worth 40%. If this score is higher, I will take it as your course grade. The latter weighing system rewards students who improve over the course.

I will follow the modern convention, in which the A range will be 90 to 100, the B range will be 80 to 90, the C range will be 70 to 80, and the D range will be 60 to 70, with plus and minus grades at the tops and bottoms of each of these ranges. If you are registered pass/fail, you must achieve at least 70 points to pass, which is the lowest score for a C−.) .

Please note: The syllabus and schedule may change at a later time, and it is your responsibility to keep up to date with it.
