office hours: Monday, Wednesday: 12:20 PM - 12:50 PM, Tuesday, Thursday: 12:55 PM - 1:55 PM, Friday: in the Toro Learning Center LIB C121: 2:50 PM - 3:50 PM, or by appointment.

Course Description: MAT 321, Probability and Statistics, covers Chapters 1-10 from the textbook.

Text:  Introduction to Probability, by C.M. Grinstead and J.L. Snell. The book can be downloaded from the internet: the whole book is here: http://www.math.dartmouth.edu/~prob/prob/prob.pdf  and you can download it chapter by chapter here: http://www.dartmouth.edu/~chance/teaching_aids/books_articles/probability_book/pdf.html.

Objectives: After completing MAT 321 the student should be able to

• understand the relationship between a question that arises in the natural, computer, economic, and social sciences and the nature of the numerical data that are needed in order to provide an answer to the question
• formulate the question in a mathematical context, set up the required mathematical procedure and carry out the required mathematical analysis and calculations, with appropriate use of a calculator, to answer the questions.
• understand why some statistical procedures are better than others in certain contexts.

Prerequisites: MAT 193 and MAT 271 or equivalent with a grade of "C" or better.

Grades: Grades will be based on three in‑class full‑period examinations (60% total), a comprehensive final examination (25%), and homework, quizzes and attendance (15%) for the remainder. The exact grading system for your section is the following: each of the three full-period exams will be graded on a 100 scale, then the sum of the scores is divided by 5 and denoted by E. Homework will be due in principle every Monday, and each homework assignment is worth 5 points. The average score for homework is denoted by H. All problems on quizzes and exams will be similar to the problems in the homework

5 to 10 minutes quizzes will be given in principle every Monday class meeting, with the exception of the review and exam days, and will be graded in class on a scale from 1 to 5. The average of the quizzes scores is denoted by Q. There are also 5 points awarded for attendance and class participation, this portion of the grade is denoted by A. The final exam will be graded out of a maximum possible 200, then the score is divided by 8 and denoted by F.

To determine your final grade  compute E+H+Q+A+F. The maximum is 100, and the grade will be given by the rule:

A: 93‑100;      A‑: 90‑92;      B+: 87‑89;      B: 83‑86;   B‑: 80‑82

C+: 77‑79;      C: 73‑76;        C‑: 70‑72;      D: 60‑69;   F: Less than 60.

Makeups: No makeup examinations or quizzes will be given. If you must miss an examination for a legitimate reason, discuss this, in advance, with me, and I may then substitute the relevant score from your final examination for the missing grade.

Accommodations for Students with Disabilities: Cal State Dominguez Hills adheres to all applicable federal, state, and local laws, regulations, and guidelines with respect to providing reasonable accommodations for students with temporary and permanent disabilities. If you have a disability that may adversely affect your work in this class, I encourage you to register with Student disAbility Resource Center (SdRC) and to talk with me about how I can best help you. All disclosures of disabilities will be kept strictly confidential. Please note: no accommodation may be made until you register with the SdRC in WH D-180. For information call (310) 243-3660 or to use telecommunications Device for the Deaf, call (310) 243-2028.

Academic Integrity: The mathematics department does not tolerate cheating. Students who have questions or concerns about academic integrity should ask their professors or the counselors in the Student Development Office, or refer to the University Catalog for more information. (Look in the index under "academic integrity".)
