All Students should be aware that the Department of Mathematical Sciences takes the NJIT Honor code very seriously and enforces it strictly. This means there must not be any forms of plagiarism, i.e., copying of homework, class projects, or lab assignments, or any form of cheating in quizzes and exams. Under the Honor Code, students are obligated to report any such activities to the Instructor.
Mathematics 333002:
probability and statistics
Spring 2007
Instructor: Prof. Dhar
Textbook: Applied
Statistics and Probability for Engineers (4th
Edition) by Douglas C. Montgomery and George C. Runger; Publisher: John Wiley & Sons © 2007 (Custom
Edition); ISBN:
0471745891
Software: To
do your homework you can use Data Analysis tools from Microsoft Excel, which is
an Addin in Excel. This tool in Excel is available on all PC labs on campus.
You could also use the Webbased statistical software statcrunch
(http://www.statcrunch.com/).
Grading
Policy: The final grade in this course will be determined as
follows:
☑ Homework + Quizzes: 

20% 
☑ 2 Common Exams: 

25%
each 
☑ Final Exam: 

30% 
Please
note that the University Drop Date March
26, 2007
deadline will be strictly enforced.
Attendance and Participation: Students must attend all classes. Absences from class will inhibit your ability to fully participate in class discussions and problem solving sessions and, therefore, affect your grade. Tardiness to class is very disruptive to the instructor and students and will not be tolerated.
Makeup Exam Policy: There will be no makeup exams, except in rare situations where the student has a legitimate reason for missing an exam, including illness, death in the family, accident, requirement to appear in court, etc. The student must notify the Math office and the Instructor that he/she will miss an exam. In all cases, the student must present proof for missing the exam, e.g., a doctor's note, police report, court notice, etc., clearly stating the date AND times.
Cellular Phones: All cellular phones and beepers must be switched off during all class times.

campus. You could also use the Webbased statistical software statcrunch
(http://www.statcrunch.com/).
Homework &
Quiz Policy: Weekly
homework problems from your textbook will be assigned. Some of these assignments
may require the use of statistical software for their solution. You must work
out not only these problems but also practice similar problems and learn the
techniques needed to solve them. The assigned problems will be posted on the web
at the address to be announced and also written on the board in class. Every
week you will have either a 510 minute quiz testing your knowledge on the
material covered in class or you will be posting your corresponding assigned
homework. Your ten best Homework/Quiz scores will be selected for 20%
of your course grade.
Exams:
There
are two common exams for all Math 333 sections and will represent 50%
of your course grade. These exams are scheduled on the following
Wednesdays:

The final exam is also common with other Math 333 sections and it represents 30% of your course grade. The Final exam is scheduled during the week of May 39, 2007. You will be given a formula sheet to use during the common exams and the final exam.
