SUMMER 2017 STAT 2300 BUSINESS STATISTICS LEAD PROFESSOR: Jenny Clements LOCAL FACILITATOR: Xianbai Li CONTACT: [email protected] OFFICE HOURS: 15:00-16:00, Rm214, Mainbuilding CLASS SCHEDULE: Tu 8:30-12:00, Wed 13:20, Fri 8:30-12:00 FINAL EXAM DATE: at the end of June TEXT: Essentials of Business Statistics, 4th Edition, Bowerman, O’Connell, Orris, Murphree PREREQUISITES: College algebra (Math 1050 at USU) with a grade of C – or better or equivalent. Each student is responsible for both knowing and satisfying the prerequisites for this course. If a student does not possess the necessary prerequisites, he or she will be dropped from the course by computer check and the notification of such a drop generally occurs after the date when any refund is possible and most likely after the ADD deadline. Please make sure you are qualified to be enrolled in this course. COURSE OBJECTIVE: The purpose of this course is to teach students statistical concepts and techniques that have applications in business and industry. Topics such as acceptance sampling and quality control are integrated with the statistical material being presented throughout the course. THE UNDERLYING CONCEPTS UPON WHICH STATISTICAL METHODS ARE BASED WILL BE EMPHASIZED AND MUST BE UNDERSTOOD. These concepts form the foundation upon which all of the analysis will be based. The primary goal is to provide the opportunity for the students to gain an appreciation of the use and value of statistical analysis as a tool in the decision-making process. In addition, the role of computer software will be examined, which will reinforce the importance of gaining a clear understanding of the fundamental statistical concepts (interpretation of the output will be the key element). STUDENT EXPECTATIONS: The CCAP program is equivalent to a USU course taught on campus at Utah State University. Lectures, course materials, homework and exams are English based. Students are expected to attend class, participate positively to class discussions/activities and submit neat/organized work on time. At all times and in all respects, students are to be courteous to the instructor and other students. Disruptive behaviors are unacceptable (e.g. extracurricular conversations, unnecessarily arriving late or leaving early, wandering in and out of class, recreational use of electronic media, etc.) Due to the cumulative nature of the course materials, students should take care to not get behind or allow concerns to go unaddressed. Students should expect to spend a minimum of 2 hours of study outside of class for every 1 credit hour (See http://www.nwccu.org/Standards%20and%20Policies/Policy%20on%20Credit%20Hour%20November%20201 2.pdf) This is a 4 credit class which translates to 8+ hours of study time a week. Textbook practice and assignments are to be an important use of this time and the intention is for you to begin working on it as soon as we start the material for that unit. If you piece out work on the prompts regularly the assignment will be manageable, you will have adequate opportunities for questions and the daily work will support the learning of the material. Do not spend a lot of time getting stuck on one part of the assignment. Do what you can, whenever you can and seek help to facilitate progression in the work. GRADES: Final course grades will be weighted as follows: Assignments: 25 % 2 Midterms: 40 % Comprehensive Final: 35 % GRADING SCALE: Grades are based on overall percentage per the above weighting scheme. The following grading scale will be used for assigning grades but may be adjusted at the discretion of the lead professor : A AB+ B BC+ C D F 100 – < 93% < 90% < 86% < 83% < 80% < 76% < 70% < 68% 93% to 90% to 86% to 83% to 80% to 76% to 70% to 68% Students are responsible for monitoring their own progress in the course and should not trust canvas until all submissions are recorded and grading schematics are properly entered. I. ASSIGNMENTS: This portion of the grade will primarily involve using Microsoft Excel as a data analysis tool. Assignments will be due at the beginning of class one week after the unit’s material is covered for it. Due dates will be announced in class. Students should work on assignments early enough to be able to get help if needed. Students will not be allowed to rework assignments after the first submission. At the local faciliators discression in class activities, exam practice worksheets and other textbook practice may be assigned for points. Students are strongly encouraged to practice exercises out of the textbook to get enough experience in the material to master it. III. EXAMS: Students may have a non-wireless capable calculator, use the textbook probability tables. Practice exam problems will be available for each learning unit. Exam prompts will be selected from the practice problems with some modification. Each exam may have a comprehensive component. EXAM I II FINAL COVERAGE Chapters 1-7 Chapters 8 – 9 10-14 and Selectively Comprehensive Suggested Time Frame 6th week 9th week PLEASE NOTE: NO MAKE UP EXAMS WILL BE GIVEN. Any conflict with an exam time must be resolved prior to the exam. Only University sponsored events, jury duty, serious illness and Military duty will be accommodated in accordance to with Utah State University policy. These situations must be supported by written documentation. ELECTRONIC DEVICES: The policy of the Department of Mathematics and Statistics is that, unless an examination requires a specific technology device, no electronic devices can be activated and positioned where they can be seen or used during a quiz or exam. In particular, cell phones must be turned off and placed inside packs, or left with the instructor. Cell phones should not be in pockets or attached to belts during an exam. The same is true of any wireless-capable device. Furthermore, headphones cannot be worn. A student found to be violating this policy would automatically receive a score of zero on that test and may be subject to further disciplinary action. Courses requiring ordinary or graphing calculators will continue to allow such devices, but the devices must not be wireless-capable devices or portable computers, personal data assistants (PDA’s), or devices otherwise able to send and/or receive voice messages, data, graphics or photographic images. In the unusual circumstances that a student needs his/her cell phone active during a test because of an emergency call is expected, the active cell phone must be left at the front of the room with the instructor. For this course, students are required to have a calculator. You will be permitted to use a calculator on the exams but sharing calculators during exams is not permitted.You do NOT need an expensive scientific calculator for this course. Something that can handle roots, exponents and other “basic” calculations will do the job. ACADEMIC INTEGRITY: Each student in this course is expected to abide by the Utah State University Code of Academic Integrity. Any work submitted by a student in this course for academic credit will be the student's own work. You are encouraged to study together and to discuss information and concepts covered in lecture and the sections with other students. You can give "consulting" help to or receive "consulting" help from such students. However, this permissible cooperation should never involve one student having possession of a copy of all or part of work done by someone else, in the form of an email, an email attachment file, a diskette, or a hard copy. Should copying occur, both the student who copied work from another student and the student who gave material to be copied will both automatically receive a zero for the assignment. Penalty for violation of this Code can also be extended to include failure of the course and University disciplinary action. During examinations, you must do your own work. Talking or discussion is not permitted during the examinations, nor may you compare papers, copy from others, or collaborate in any way. Any collaborative behavior during the examinations will result in failure of the exam, and may lead to failure of the course and University disciplinary action. AMERICANS WITH DISABILITIES ACT: Americans with Disabilities Act: Title II of the Americans Disabilities Act mandates that all State and Local Government programs be administered in such a manner as to protect qualified individuals with disabilities from discriminatory treatment. Utah State University complies with this policy, and therefore: “If a student has a disability that will likely require some accommodation by the instructor, the student must contact the instructor and document the disability through the Disability Resource Center (DRC), during the first week of the course. Any requests for special considerations relating to attendance, pedagogy, taking of examinations, etc. must be discussed with and approved by the instructor. In cooperation with the DRC, course materials can be provided in alternative formats—large print, audio, diskette or Braille.” TOPICS: The following includes a rough schedule with a list of topics to be covered during the semester and concepts that should be emphasized. The number of weeks suggested do not add up to 15 to permit time to review for and take exams. Unit 1: Introduction and Descriptive Statistics (Chapters 1-3) 1 week Brief overview of selected topics. Students are encouraged to read chapter material for more in depth understanding. Selecting a random sample. Population data versus sample data. Distinguish between qualitative and quantitative data. Frequency distributions, bar charts and histograms. Measures of central tendency and variability with an emphasis on the mean, variance, standard deviation and proportion. Unit 2: Probability (Chapters 4-7) 4 weeks Probability rules and relationships. Conditional probability and Independence. Bayes theorem. Discrete and continuous probability distributions. Expectation and Variance. Use of formulas, tables and Excel to get probabilities for the Poisson, Binomial and Normal Distribution. The sampling distribution of the sample mean and sample proportion. Unit 3: Single Sample Inference (Chapters 8-9) 4 weeks Confidence intervals and hypothesis tests for the sample mean, proportion and variance from one population. Type I, Type II errors.
