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.

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.
