Attendance is not required for this class. However, students are responsible for all information given in class, regardless of his/her attendance.
Final grades online access:
On any day, if you disrupt the class you will be asked to leave the classroom and marked absent. You may also be reported for further disciplinary actions. Disruptive behaviors include --but are not limited to -- talking, making inappropriate jokes, using phones in class, leaving class to answer phone, or performing other tasks that are not related to class work.
Student Evaluation of Teaching Effectiveness:
The Student Evaluation of Teaching Effectiveness (SETE) is a requirement for all organized classes at UNT. You must participate in this online short survey at the end of the semester.
The University of North Texas makes reasonable academic accommodation for students with disabilities. Students seeking accommodation must first register with the Office of Disability Accommodation (ODA) to verify their eligibility. If a disability is verified, the ODA will provide you with an accommodation letter to be delivered to faculty to begin a private discussion regarding your specific needs in a course. You may request accommodations at any time, however, ODA notices of accommodation should be provided as early as possible in the semester to avoid any delay in implementation. Note that students must obtain a new letter of accommodation for every semester and must meet with each faculty member prior to implementation in each class. For additional information see the Office of Disability Accommodation website at You may also contact them by phone at 940.565.4323.
Students are responsible for meeting all university deadlines (registration, fee payment, prerequisite verification, drop deadlines, etc). See the printed Schedule of Classes and/or University Catalog for policies and dates.

Required Text: Probability & Statistics for Engineering and the Sciences, by J. L. Devore. There are two options for purchasing this text. The second option is cheaper; however, this only provides temporary online access to the textbook, so that you would neither be able to use a physical hard copy of the book this semester nor permanently add it to your bookshelf after completing the course.

Bundle: Text + Enhanced WebAssign + Start Smart Guide for Students + Enhanced WebAssign Homework with eBook Printed Access Card for One Term Math and Science. ISBN 978-1-111-65549-5. Can be purchased for $191.49 from Can also be purchased at the UNT Bookstore (price not available at this time).

Book + Enhanced WebAssign. ISBN 978-1-285-85804-3. Can be purchased for $75 from

Strongly Recommended: Lecture notes for the semester can be purchased from the Eagle Images Print Center for approximately $20. The Eagle Images Print Center is in room 124 of the University Service Building (USB), which located near the Fouts Field Parking Lot. This is not a convenient location, but offering them for sale elsewhere would increased the price of the lecture notes significantly. The Mean Green (stop 7 on the map) and Campus Cruiser shuttles both stop at USB. You should enter through the north door (that is, the door that isn’t facing Fouts Field) to easily get to the Print Center.

Technology: You will be expected to bring to class --- including exams --- either a laptop computer with a spreadsheet program (such as Microsoft Excel or Open Office Calc) or else a calculator that can perform multiple statistical functions. In class, I will demonstrate how to use Microsoft Excel and a TI-83 Plus to perform various statistical functions. If you have some other kind of calculator, you are welcome to ask me before or after class about how to use its statistical functions.

What You Should Do Immediately

Please read the Enhanced WebAssign handout for instructions about how to enroll yourself in the appropriate section of Math 3680. In particular, you will need to visit and use the following Class Key Code:

unt 4650 9956

Click here for further instructions about getting started with Enhanced WebAssign.

I strongly encourage you to get started with Enhanced WebAssign as soon as possible. If you delay, you run the risk of unforeseen technical problems that could prevent you from completing the first assignments (both due on Friday, September 5, with a bonus possible if submitted by September 3).

While Enhanced WebAssign is required for the course, it is my understanding that, at the start of the semester, you have a 14-day grace period to use Enhanced WebAssign for free. After this grace period, a code must be entered to continue to use Enhanced WebAssign.

Student Responsibilities

Disruptive behavior that interferes with an instructor's ability to conduct a class or other students' opportunity to learn is unacceptable and will not be tolerated in any instructional forum at UNT. Any student engaging in such behavior will be directed to leave the classroom and may be referred to the Center for Student Rights and Responsibilities to be considered whether the student's conduct has violated the Code of Student Conduct. The university's expectations for students’ conduct apply to all instructional forums, including university and electronic classroom, labs, discussion groups, field trips, etc.

• You should read over this syllabus carefully, as I will hold you responsible for the information herein.

• Youare expected to read the chapters carefully, including the examples in the book.

• Youare responsible for obtaining all handouts. If you are absent when handouts are given, it is your responsibility to obtain copies.

You should begin to work now. Frequent practice is crucial to the successful completion of a mathematics course. Cramming at the last minute will certainly lead to failure. Typically, successful students wouldspend an hour or two after each lecture with classmate(s)to review the lesson and work homework problems. Instead of waiting until the last minute,such students work on the assignments, read their textbooks, and make learning notes daily.

• WARNING: If you are in academic trouble, or in danger of losing your financial support, or if your parent or guardian is expecting a certain grade at the end of the semester... start working today! I will refuse to listen to any pleas at the end of the semester. You will receive precisely the grade that you earn.

Test Schedule and Grading Policies

The following schedule is tentative and is subject to capricious changes in case of extracurricular events deemed sufficiently important to the upper administration.

Three Tests:Test 1: (Chapter 1-3): Tuesday, February 24

Test 2: (Chapter 4-7): Tuesday, March 31

Test 3: (Chapter 8, 9): Thursday, April 30

Comprehensive Final Exam and time: Monday, May 11, 1:30-3:30pm

Grades: A 90%-100%, B 80% - 89%, C 70% - 79%, D 60% - 69%, F below 60%

Academic Dishonesty: Cooperation is encouraged in doing the homework assignments but not allowed on the tests/exams. If you are caught cheating, you will be subject to any penalty the instructor deems appropriate, up to and including an automatic F for the course. Furthermore, a letter will be sent to the appropriate dean. Refer to the following university site for the official policy with regards to academic dishonesty. The website is:

• The grade of "I" is designed for students unable to complete work in the course but currently passing the course. The guidelines are clearly spelled out in the Student Handbook. Before asking, you should read these requirements.

Exam Policies

• I expect to give testson the dateslisted above. However, these are tentative dates. I will announce the exact date of each test in class.

• After a test is returned in class, you have 48 hours to appeal your grade. I will not listen to any appeals after this 48-hour period.

NO MAKE-UP TESTS WILL BE GIVEN. A test may be taken prior to the scheduled date. I request a week’s notice for this accommodation via email. In the event of a schedule conflict with a university function, dental/physician’s appointment, wedding, formal, etc., you must take the test early. If you do not take a scheduled test, a zero will be recorded for that test and a notice may be sent through the registrar’s office.

There are three in-class tests. If your final exam score is higher than one of your in-class test scores, then that in-class testscore will be replaced with final exam score. If you miss an in-class test, a zero will be recorded for that testscore and your final exam score will replace that one zero. If you receive a zero for cheating on a test, the final exam score will NOT replace that zero. The final exam score can count as 20% of the course grade or 40% of the course grade. Again, NO MAKE-UP TESTS WILL BE GIVEN FOR ANY REASON EVER.

• The Final Examination will be comprehensive in the sense that problems may come from any sections that have been covered during the semester.

• Your final exam can be exempted; if your course average before the final is 93.00 or higher, you will be given an A for the course.

• I reserve the right to test you on problems which are generalizations of material covered in the class and/or in the text. In short, the problems may not look exactly like the ones in the book.

• Everything that I say in class is fair game for exam material. You will be responsible for everything unless I advise you to the contrary.

Homework Policies

  • All homework assignments can be logging into

oEach part of each exercise can be attempted up to 10 times. In other words, you could submit answers to part (a) of Exercise #1 up to 10 times, and then you could move on to attempt part (b).

oYour last submission will count as your final answer.

oYou can save your work without using a submission.

oSome exercises will use randomization. In other words, it’s possible that every student will have slightly different questions with accordingly different answers.

  • Due dates

oHomework will be due every Friday at 11:59 pm.

oA 5% bonus will be awarded to students who complete their homework more than 48 hours before the due date.

oIf requested no more than a week after the original due date (i.e., by the following Friday at 11:59 pm), it is possible to receive an automatic extension on homework through Enhanced WebAssign. Any work done after the automatic extension can be submitted for half credit as long as it completed within 24 hours of the request.

• When computing the final grade, I will drop the three lowest homework gradesbefore computing the average. I have this policy in case you get sick,have a family emergency, etc., during the semester. You will still be responsible for the material in such assignments during the examinations.

• Because of this policy, I will NOT give extensions on homework assignments, nor will I accept late assignments for any reason whatsoever.
