Question 1
In a class where the exam averages are normally distributed, the mean score is 75 and the standard deviation is 10. If you want to find out the probability that a randomly picked student has scored 85 or above, what is the z value that you should look up on the normal distribution table?


Question 2
According to a report by Scarborough Research, the average monthly household cellular phone bill is $73. Suppose local monthly household cell phone bills are normally distributed with a standard deviation of $11.
a. What is the probability that a randomly selected monthly cell phone bill is less than $95?

b. What is the probability that a randomly selected monthly cell phone bill is between $62 and $84?


Question 3
A Travel Weekly International Air Transport Association survey asked business travelers about the purpose for their most recent business trip. Nineteen percent responded that it was for an internal company visit. Suppose 950 business travelers are randomly selected.
a. What is the probability that more than 20% of the business travelers say that the reason for their most recent business trip was an internal company visit?

b. What is the probability that between 18% and 21% of the business travelers say that the reason for their most recent business trip was an internal company visit?

Students and faculty of Barton Community College constitute a special community engaged

in the process of education. The College assumes that its students and faculty will

demonstrate a code of personal honor that is based upon courtesy, integrity, common sense,

and respect for others both within and outside the classroom.

Plagiarism on any academic endeavors at Barton Community College will not be tolerated.

The student is responsible for learning the rules of, and avoiding instances of, intentional or

unintentional plagiarism. Information about academic integrity is located in the Student


The College reserves the right to suspend a student for conduct that is determined to be

detrimental to the College educational endeavors as outlined in the College Catalog, Student

Handbook, and College Policy & Procedure Manual. [Most up-to-date documents are

Business Calculus is an approved general education course at Barton Community College,

which can be used to fulfill degree requirements as a fundamental mathematics course.

Business Calculus is designed to provide business and economic majors with a basic

understanding of differential and integral calculus and its applications in business and

economics. Students needing calculus but who are not business majors or are uncertain of

their major should enroll in the 5 credit Calculus I, MATH 1832. Any student whose major

program requires two or more calculus courses should also take MATH 1832 since it is a

more in-depth study of differential and integral calculus.

This course transfers well to most of the regent universities as a three credit hour

Basic/Business Calculus. However, requirements vary among institutions, and even within

departments, and often without much notification. Thus, it is the student’s responsibility to

be in contact with the transfer institution throughout his/her tenure at Barton Community

College to insure that the student is enrolling in the most appropriate set of courses for the

transfer program.


Barton Community College is committed to the assessment of student learning and to quality

education. Assessment activities provide a means to develop an understanding of how

students learn, what they know, and what they can do with their knowledge. Results from

these various activities guide Barton, as a learning college, in finding ways to improve

student learning.

MATH1831 Business Calculus is designed in weekly (9-week session) units. Students must

complete any graded assignments by the due date of each lesson. In the event of computer or

network problems, it is the responsibility of the student to contact the Canvas Helpdesk

( -or- 1-844-711-0949) for technical assistance and email the

instructor of the situation.

Failure to complete a graded assignment before the deadline will result in a late penalty on

that assignment. The penalty applies regardless of reason (e.g. computer or network

problems, personal situations, work conflicts, etc.), so plan to complete graded assignments

before the deadline in order to leave yourself some time for unforeseen circumstances.

Failure to complete a graded assignment prior to the end of the course will result in a

score of zero (0).

Courteous, professional conduct on the Internet is mandatory. Disruptive and/or offensive

behavior will result in dismissal from the course.

All students are required to produce their own work on ALL assignments. Evidence of

cheating will result in at least a zero for that assignment. Additionally, the instructor may,

without cause, require the use of Panopto web-cam video recording for all remaining

assignments for an individual student or the class as a whole.

It is really important to practice the mathematics. The homework sets for each section can be

found embedded within the course. You need to score a minimum of 50% on each homework

set in order for the Unit Quiz/Test to open. Make sure that you complete the homework sets

in plenty of time before the due date for the Unit Quiz/Test. A 20% deduction will be made

on any Homework Set completed within a week after the due date. After one week, the score

will be and remain a zero.


There is also a Show Work problem set that is a cross-section of the entire unit. In the Show

Work problem set, not only must you input your answer correctly but you must show your

work for each problem like you would if a teacher was collecting your written work in a face-

to-face class and looking at your steps to solve a problem.

You can show your work two major ways. (1) Upload a picture of your handwritten work

onto the whiteboard. This is the recommended way of showing your work. Please make sure

that your picture is clear (not fuzzy) so that your handwriting can be clearly read. (2) Write

on the whiteboard. Each Show Work question has a whiteboard and “pens” that you can write

with on it.

In order for the weekly tests to open, you have to score a 50% on the Show Work assignment

too. The Show Work assignment has to be graded by your instructor personally. Since the

instructor is not constantly in the course there may be a delay. The instructor will

communicate with you concerning the days and times they will be entering the course to

grade the Show Work questions. Make sure that you have them completed by one of those times otherwise you may not get access to the test.


There will be at least one Unit Quiz/Test over each chapter and a Final. All of these

assignments can be found in My Math Lab. The final exam is comprehensive. You should

complete each quiz/test by the end of the corresponding chapter/unit; quizzes/exams may be

completed after the chapter/unit but will receive a late penalty of 20% and must be completed

within a week of the due date. After a week, the score will be a zero and there is no chance of

making up the assignment. A score of zero (0) is recorded for all quizzes/tests not completed

by the end of the course.

All Unit Quizzes and Tests must be proctored using the Panopto software. Failure to do so

will result in a zero.


Threaded discussions include the muddiest points. Grading will be based on participation,

completion and quality of the posts. You must post a question and respond to two others.


Every student must complete the pretest and post test. A student earns full credit for

attempting the Pre-Test. The Post Test will be graded on the correctness of the responses.

FINAL EXAM There is a comprehensive final exam for this course. The final exam must be proctored using

the Panopto software. Failure to do so will result in a zero.

Orientation Week 5%

Muddiest Point/Threaded Discussions 5 %

Homework Sets 10%

Show Work 10%

Quizzes/Tests 50 % Post Test 5 %

Final Exam 15%

Letter grades will be determined using the following scale:

90-100% A

80-89.99% B

70-79.99% C

60-69.99% D Below 60% F


The Barton Community College Course Attendance Policy is available online for student

reference. The Barton Community College Grade and Attendance Reporting Policy is also

available online for student reference. Students should read both documents to familiarize

themselves with the official attendance and grade reporting policies of the college.

Class attendance in Barton distance learning classes is measured primarily by completion of

assignments and participation. I will measure your participation by you having: (1)

successfully logged in each lesson, (2) completed all assignments by the end of the lesson,

and (3) emailed questions when you are having difficulty.
