Prerequisites: Three and a half years of high school math, including pre-calculus or advanced algebra, and appropriate placement test score, or MTH 141 with a grade C or better. E. Catalog Description: Covers descriptive statistics, data presentation, analysis, and interpretation; sampling techniques, hypothesis testing for single and multiple samples; analysis of variance; selection of appropriate parametric and nonparametric statistical tests; correlation and regression, and multi-step decision making techniques in a business environment. Students use a statistical computer software package to analyze and interpret data.

V Classroom Policies/Procedures A. General Information Sheet: see attachment. B. Each student is responsible for adhering to the Code of Student Conduct as stated in the college catalog. C. Withdraw policy A student who does not withdraw officially from a course may receive a grade F, depending on course progress or course attendance, which will become a part of the student s permanent record. The withdraw date is listed in the General Information Sheet. D. Cell-phone policy Faculty, staff, students and college visitors may not use and must silence cell phones, pagers, and other communication devices in all instructional areas which include: all labs and classrooms during instructional sessions, the Learning Resources Center/Library, the Assessment Services Center (B101), and other areas so designated by the college. E. Cheating/plagiarism policy (any academic dishonesty) Any occurrence of cheating/plagiarism (any academic dishonesty) will be officially documented by filling out the appropriate paperwork as designated by the sub-division office. Any person involved in any sort of cheating/plagiarism (any academic dishonesty) will receive a score of 0 on any assignment in question, and, at the discretion of the instructor, automatic failure for the course with no option to withdraw. F. Attendance and participation policy Class attendance and participation are essential for mastering the course objectives and for making successful progress in this class. Attendance will be taken each class at the beginning of the class period. In case of an absence from a class for any reason, student is responsible for the material covered in class as well as material in the textbook. More than three absences will result in automatic failure of the course. A student is not allowed to leave the classroom while taking a quiz or a test. G. Make-up policy There is NO MAKE-UP (earlier or later) for any reason for any missed test/quiz/activity/project or any other assignment. Any missed/late assignment will earn a score of zero. See Grading/Evaluation for more details. At the instructor s sole discretion, a student may elect to take an exam prior to the scheduled test date in the testing center by giving the instructor at least one week s notice. Students are limited to one test taken in the testing center per semester. H. Extra Credit policy No extra credit will be available for this course. There is free math tutoring by mathematics faculty and qualified students available in the Academic Skills Center in B260 on a walk-in basis. (See General Information Sheet). You are encouraged to see me if you are having difficulties mastering the objectives of this course. I will be very happy to meet with you to discuss any problems you are having. - 5 -
VI Grading/Evaluation A. Homework You should plan to spend at least 8 hours per week outside of class studying and doing homework. Homework will be assigned for all material covered in class. Homework may include problems from the book as well as any other problems assigned by the instructor (from any source, such as activities, handouts, etc). Any homework problem can be discussed in the beginning of the following class period. This homework is meant to reinforce the concepts presented in a class. You are encouraged to discuss these problems with your fellow classmates. Homework is expected to be completed with detailed solutions as assigned. Homework is essential in mastering the objectives of this course, and all assignments will be due on the date of the exam for those chapters. Homework assignments will not be collected or graded. B. Tests There will be 4 in-class unit tests given throughout the semester. Each test is worth 100 points. The highest three unit test scores will be used in the calculation of the final grade, and the lowest score will be dropped. A student who is late for an exam will not be allowed to take the exam if at least one other student has already finished his or her exam. Any missed unit test will result in a score of zero for that exam. There is NO MAKE-UP for any missed unit test. C. Final Exam The final is mandatory and will be a cumulative exam worth 100 points. A MISSED FINAL EXAM FOR ANY REASON WILL EARN A SCORE OF ZERO. There is NO MAKE-UP (earlier or later) for the final. Final Exam may contain two parts. If Final Exam has two parts, then Part 1 will be worth 20% of the Final Exam. Part 1 may be given in the last day of classes before the finals week. See schedule for more details. Part 2 will be worth 80% of the Final Exam. Part 2 will be given during the scheduled finals week. See schedule for more details. The following is a summary of the cumulative point scales used in determining your final grade. Points Earned Percent Final Grade 360 400 90 100 A 320 359 80 89 B 280 319 70 79 C 240 279 60 69 D 0 239 0 59 F - 6 -

Late registration does not exempt the student from adhering to the attendance requirements in the course syllabus. Make-up work or work submitted late due to absence (including an instructor's decision to award less than full credit for work submitted late) will be handled at the discretion of the instructor in accordance with the course syllabus. Students not regularly attending class are strongly advised to withdraw officially from the course. Students who do not withdraw officially may receive a grade of "F" for the course, which will become a part of the student's permanent record. Students who must be absent due to prolonged illness or extended emergency should notify their instructor(s) immediately for the purpose of determining a plan of action appropriate to the situation.
