# MATH 250 A02(04735), Winter 2006

## Introduction to Probability and Statistics I

Catalog Description:
Organization of data, central tendency and dispersion, probability, concept of random variables, binomial and normal probability distributions. No credit for 250 if already credit for 450A, PSY 120, PSY 121, PSY 221, ISE 304, or ISE 305.
Prerequisites:

Text:
Statistics--Principles and Methods, fourth edition, by Richard A. Johnson, and Gouri K. Bhattacharyya; John Wiley & Sons, Inc., 2001.
Calculator:
A scientific calculator is required. It does not need to be able to graph.
Homework:
Several problems from each section of the book are assigned. These problems will not be collected or graded, but you will need to do them in order to learn.
Good Problems:
Six Good Problems are assigned, and will be collected and graded. These are homework problems that will be graded half on content and half on presentation. The idea is to practice writing mathematics regularly but in small pieces.
Tests:
There will be four mid-term tests, in class. A calculator is needed.
Final Exam:
The final exam is on Tuesday 14 March at 8:00am in our regular classroom. A calculator is needed.
Each Good Problem is worth 1 unit, each test is worth 2 units, and the final is worth 4 units. Your lowest 2 units will be dropped and then your average is computed and a 90% guarantees you at least an A-, 80% a B-, 70% a C-, and 60% a D-.
Missed or Late work:
Only reasons given in advance of a missed test will be considered; otherwise a score of 0 will be given. Late Good Problems are penalized 5% for each 24 hour period or part thereof, excluding weekends and holidays. You can resubmit good problems to improve your score, but the late penalty will apply.
Attendance:
You are strongly encouraged to work together on the homework. You can work together on the Good Problems, but you must acknowledge in writing what help you received and from whom. The tests and final exam must be your own work, and without the aid of notes, etc. Dishonesty will result in a zero on that work, and possible failure in the class and a report to the university judiciaries.
Special Needs:
If you have specific physical, psychiatric, or learning disabilities and require accommodations, please let me know as soon as possible so that your learning needs may be appropriately met.
Learning Resources:
• A collection of online resources http://www.statsci.org/teaching.html
• An (advanced) online textbook http://www.statsoftinc.com/textbook/stathome.html
• ## Schedule
