Please notice that you are required to take a (five-minute) syllabus quiz by January 17th, 2021, which would require to open an account in MH Connect before the January 24th deadline.
EXPECTED LEARNING OBJECTVIES
- - Use continuous probability distributions and sampling distributions in a variety of business applications. (LG2, LG3, LG6, LG12)
- Construct and interpret interval estimates (LG2)
- Perform hypothesis testing for one and two samples
- Estimate regression models, evaluate the results of regression models, and use the results for prediction and forecasting. (LG2, LG3, LG12)
- Use Microsoft Excel to generate descriptive statistics and perform regression and correlation analysis (LG2, LG3, LG12).
- Note: A complete list of expected learning goals (LG) for the Economics Department can be found at the department web site (http://www.westga.edu/econ/1718.php).
Evaluation of this course will be based on the following assignments and activities:
- Quizzes (syllabus and one for each chapter assigned).
- Homework assignments (one per chapter).
- Excel assignments (one per selected chapters).
- Regression assignment (based on material from chapter 14).
- No final exam is given.
This is an online course. However, it is not a “work-at-your-own-pace” type of course. There are specific dates to take quizzes and complete assignments. If you anticipate having problems submitting work on time and/or taking quizzes on the specific dates provided, you should not take this course. There will not be a change to those dates to either earlier or later dates.
Important: a significant number of exercises found in both the homework and Excel assignments must be solved using Excel. You need to have Excel 2013 or later version installed in your computer. Both assignments are due by 8 am (not 11:59 pm) on the day quizzes open. Advice: complete assignments ahead of time. If you decide to take assignments until just before the deadline, you assume the responsibility for the risks involved such as sudden computer or internet problems. The deadlines will not be changed unless MH Connect or D2L experience officially-reported outages or technical problems.
Quizzes: During the semester, you will be required to take a syllabus quiz and one quiz per chapter. Module I: chapters 3, 7 & 8, module II: chapters 9 & 10, module III: chapters 11 & 12, and module IV: chapters 13 & 14. All quizzes will be available in MH Connect.
Quiz-taking rules: You can use all the notes, tables, slides, etc. However, you are expected to work individually.
Each quiz is available during two days right after the deadline to submit homework and Excel assignments. Friday and Saturday for modules 1-3 and Sunday and Monday for module 4. You may take them any time during those two days up until 11:59 pm of the last day. These dates will not be changed, regardless of reason. Your grade average will be calculated after dropping the lowest two grades. Grades for chapters 13 and 14 (module IV) will not be dropped.
Maximum time allowed for each quiz: thirty minutes. Maximum time allowed for the syllabus quiz: five minutes.
More details provided below.
A homework is assigned per chapter and it contains a set of questions based on exercises found in the textbook. It has no time limit and you can always save your answers and continue later. As you respond each question, you have the “check my work” option to verify whether it is correct or not. After a homework is submitted, answers to exercises will not be provided. If you want to review similar exercises, study the slides, practice exercises, and odd-numbered exercises found in Appendix D of the textbook (answers included). Homework assignments are available at the Connect (MH) website. Advice: submit this assignment until you have studied the corresponding material and have solved a few exercises from each section.
Weight of assignment: 30%. The lowest two grades will be dropped. Grades for chapters 13 and 14 (last two chapters) will not be dropped.
For a selected number of chapters, you need to solve exercises using Excel. This assignment has no time restriction and “check my work” is not available. Excel assignments are available at the Connect (MH) website. Advice: submit this assignment until you have studied the corresponding material and have solved a few exercises from each section. Chapters included: 3, 9-14. Weight of assignment: 20%. No grades will be dropped.
Practice (and Solved) Exercises
Solved Exercises: I strongly advise you to study the material by solving the odd-numbered exercises found in Appendix D of the textbook. Answers are included. Steps to access the Appendix: click the ebook “Lind, Statistics Techniques in Business and Economics, 17e (eBook)”, “table of contents (three horizontal lines on top left of screen)”, scroll down and click on “Appendix D.”
Some of those exercises are also shown in the "practice exercises" of each chapter.
This assignment is not graded but I highly recommend you to study with it.
As mentioned before, you are required to take a quiz for every chapter assigned. Each quiz consists of four true/false questions, four multiply-choice questions, and two exercises similar to the ones assigned in the homework. The maximum time allowed is 30 minutes. Your quiz grade will be calculated after dropping the lowest two grades. Quiz grades for chapters 13 and 14 will not be dropped.

Course Policies and Resources
Academic dishonesty on any exam will result in a zero on that exam, a note recording the incident on the student's permanent record and the student reported to Student Services for appropriate disciplinary action by the University. Students not familiar with what constitutes academic dishonesty or those unfamiliar with the appeal procedure regarding academic dishonesty should refer to the UWG Undergraduate Catalog.
For this course, the most important issue is that you have to take each quiz individually. If you make any kind of consultation with another person or website while taking a quiz, it will be considered cheating and your grade will be zero.
Final Letter-Grade Assignment (strictly enforced):
0 – 59.99: F
60 – 69.99: D
70 – 79.99: C
80 – 89.99: B
90 – 100: A
After assignments listed in the syllabus are completed and past due, no extra assignments, bonus questions or extra test will be given. Your letter grade will be assigned according to the scale shown above and will not be changed. I will not respond to emails requesting further adjustment or extra assignments.
To learn the topics of this course, students should use the following resources or tools:
- ebook and chapter slides
- Videos recorded by your instructor discussing every learning objective of every chapter.
- Videos recorded by your instructor discussing Excel commands to solve problems.
- Videos provided by MH Connect demonstrating the use of Excel commands to solve problems.
- Odd-numbered and practice exercises, which include solutions.
Having read the Honor Code for the University of West Georgia, I understand and accept my responsibility to uphold the values described therein and to conduct myself in a manner that will reflect the values of UWG and the Richards College of Business so as to respect the rights of all UWG community members.

At the University of West Georgia, we believe that academic and personal integrity are based upon honesty, trust, fairness, respect, and responsibility. Students at West Georgia assume responsibility for upholding the honor code. West Georgia students pledge to refrain from engaging in acts that do not maintain academic and personal integrity. These include, but are not limited to, plagiarism, cheating, fabrication, aid of academic dishonesty, lying, bribery or threats, and stealing.
The University of West Georgia maintains and monitors a confidential Academic Dishonesty Tracking System. This database collects and reports patterns of repeated student violations across all the Colleges, the Ingram Library, and the School of Nursing. Each incidence of academic dishonesty is subject to review and consideration by the instructor, and is subject to a range of academic penalties including, but not limited to, failing the assignment and/or failing the course. Student conduct sanctions range from verbal warning to suspension or expulsion depending on the magnitude of the offense and/or number of offenses. The incident becomes part of the student’s conduct record at UWG.
Additionally, the student is responsible for safeguarding his/her computer account. The student’s account and network connection are for his/her individual use. A computer account is to be used only by the person to whom it has been issued. The student is responsible for all actions originating through his/her account or network connection. Students must not impersonate others or misrepresent or conceal their identities in electronic messages and actions. For more information on the University of West Georgia Honor Code, please see the Student Handbook.
UWG Email Policy
University of West Georgia students are provided a MyUWG e-mail account. The University considers this account to be an official means of communication between the University and the student. The purpose of the official use of the student e-mail account is to provide an effective means of communicating important university related information to UWG students in a timely manner. It is the student’s responsibility to check his or her email.
Credit Hour Policy
The University of West Georgia grants one semester hour of credit for work equivalent to a minimum of one hour (50 minutes) of in-class or other direct faculty instruction AND two hours of student work outside of class per week for approximately fifteen weeks. For each course, the course syllabus will document the amount of in-class (or other direct faculty instruction) and out-of-class work required to earn the credit hour(s) assigned to the course. Out-of-class work will include all forms of credit-bearing activity, including but not limited to assignments, readings, observations, and musical practice. Where available, the university grants academic credit for students who verify via competency-based testing, that they have accomplished the learning outcomes associated with a course that would normally meet the requirements outlined above (e.g. AP credit, CLEP, and departmental exams).
Mental Health Support
If you or another student find that you are experiencing a mental health issue, free confidential services are available on campus in the Counseling Center. Students who have experienced sexual or domestic violence may receive confidential medical and advocacy services with the Patient Advocates in Health Services. To report a concern anonymously, please go to UWGcares.
If you are a student having difficulty with English language skills, and / or U.S. culture is not your home culture, specialized resources are available to help you succeed. Please visit the E.L.L. resource page for more information.
Proctored Exams/Online Instruction: Students should be aware and plan ahead for the possibility of having to complete all courses and/or exams online or in a proctored environment. This means talking with your instructors about what minimum technical requirements (software and hardware) will be required should your class move online or a student's personal needs dictate. This also includes making plans for internet access at whatever location participation may occur.
Virtual or in-person proctored exams, if your instructor should require them, may result in an additional cost to the student. Please discuss these details with your instructor or see the information provided here.
Face Coverings: Effective July 15, 2020, University System of Georgia institutions, including the University of West Georgia, will require all faculty, staff, students, and visitors to wear an appropriate face covering while inside campus facilities/buildings where six feet social distancing may not always be possible. Face covering use will be in addition to and is not a substitute for social distancing.
Face coverings are not required in campus outdoor settings where social distancing requirements are met. Anyone not using a face covering when required will be asked to wear one or must leave the area.
Reasonable accommodations may be made for those who are unable to wear a face covering for documented health reasons.
