STAT212: BUSINESS STATISTICS II
Course Outline, Semester 062
(Fully coordinated course)
Instructor: Esam Al SawiOffice: B4-147-4Phone: 1887E-mail: alsawiesWeb Page: Office Hours:
Text and Package:
1. Business Statistics: A Decision-Making Approach, 6th edition by Groebner, D., Shannon P., Fry, P. and Smith, K., Prentice Hall (2004).
2. MINITAB Statistical Package will be used.
3. Scientific calculator with statistical functions in every class and exam.
Course Objectives:
Introducing basic concepts of probability and statistics to business students. Emphasis will be given on the understanding of the nature of randomness of real world problems, the formulation of statistical methods by using intuitive arguments and thereby making meaningful decisions.
Assessment
Assessment for this course will be based on homework, lab work, attendance, three major exams and a comprehensive final exam, as in the following:

Important Note: The homework can be submitted anytime earlier but when the chapter is completed in a certain class, it must be well understood, by all the students, that the homework for that chapter must be submitted in the Saturday just after that and no need for an announcement in advance.

Notes:
Classes will meet in the lab for MINITAB whenever it is needed and possible.
Attendance on time is very important. Therefore, % will be deduced for each one absence.
Mostly, attendance will be checked within the first five minutes of the class. Entering the class after that, is considered as one late, and every two lates equals to one absence.
In accordance with the university undergraduate bulletin, ten unexcused absences will result in a grade of DN.
All contacts or announcements between the instructor and the students are supposed to be held on the WebCT, so the student must check his WebCT inbox at least once a day.
Home Work Problems:
Ch-8: 8.19, 8.37Ch-9: 9.30, 9.41Ch-10: 10.11, 10.44Ch-12: 12.12, 12.27Ch-13: 13.12, 13.27, 13.38Ch-14: 14.8, 14.18, 14.25, 14.34, 14.43Ch-15: 15.12, 15.32, 15.43
General Note on Problem solving in Homework, and Exams:
To effectively learn statistics, students need to solve problems in statistics and analyze data.
The selected homework problems above are designed to prepare you for major exams, and the final exam. Therefore, you are strongly encouraged to complete them.
Never round your intermediate results to problems when doing your calculations. This will cause you to lose calculation accuracy. Round only your final answers and you should not round less than 4 decimal places unless required otherwise.
Some lab times are reserved for student practice on MINITAB.
It is to the students advantage to keep a binder for storing class notes, homework, and other graded assignments. Students who are organized will find it easier to find important materials when studying for exams.
A formula sheet and statistical tables will be given for you in every exam, so you only need to bring with you pens, pencils, a sharpener, an eraser, and a calculator.
Student Learning Outcomes:
Students are expected to
Know the correspondence between levels of measurement and statistical procedures.
Know the assumptions underlying statistical procedures.
Select the appropriate statistical procedure for various applied business situations.
Accurately compute procedures manually and by MINITAB and interpret the results of these statistical procedures.
