**Course Description for Math 247/124 Credit Hours: 3.0 & 1.0**

The basic concepts of statistical analysis used in business decision-making, including probability and how uncertainty is dealt with in real life. The student will analyze and work out simple problems and should be able to recognize instances in which statistical techniques have been misused. The following concepts and statistical techniques are included: measures of central tendency and variability; random variables and probability distributions; binomial, normal and sampling distributions; estimation; tests of hypothesis; chi-square tests; linear regressions and correlation; and one-way analysis of variance.

TWO SEPARATE GRADES WILL BE ISSUED.

**Materials Required:**

** ** Textbook, loose-leaf paper, pencils

Suggested: Graphing calculator, notebook/folder

** **

**Grading Policy: **

**Math 247**

Grades will be based on writing projects, homework, quizzes, and tests.

Writing projects= three papers will be completed (about 3% final grade)

Homework = homework will be completed online (about 9% final grade)

Quizzes = approximately 30 points per chapter (about 33% final grade)

Tests = approximately 100 points per chapter (about 55% final grade)

*(Note: The lowest quiz score and homework score will be dropped.)*

* *

**Math 124**

** ** Grades will be based on computer projects using Excel, PHStat, and data.

** ** Projects = approximately 20 points per chapter

**Grading Scale**

A = 90%- 100%

B = 80% - 89%

C = 70% - 79%

D = 60% - 69%

F = Below 60%

Note: When there is a question concerning the point value given on a graded quiz or exam, please write a response to the instructor and submit this within a week of receiving the paper. Class time is not the appropriate place to discuss this issue.

**Cell Phones:**

** ** For the integrity of this class, cell phones may not ring or be used during quizzes and tests.

**Attendance:**

Attendance is expected and is beneficial for successful completion of this course. Students are expected to attend ALL scheduled class periods. If more than two weeks of classes are missed without a valid excuse, a student may be withdrawn from the class with an F. Students will not be allowed to make up homework, quizzes, or tests. For emergency situations, approval MAY be given for a missed class. Arrive on time and sign the attendance sheet for each class to receive full credit for course work that day. If you plan to withdraw from the course, it is your responsibility to make these arrangements!

If you miss less than 2 classes prior to midterm, you may have the opportunity to complete an extra credit paper worth 10 points. If you miss less than 2 classes from midterm to April 26, you may complete another extra credit paper worth another 10 points.

**Tardiness:**

It is disrespectful to others to interrupt a scheduled class. Arriving late for class will affect your grade. Participation scores will be lowered, homework may not be accepted, and extra time will not be given to complete quizzes or tests.

**Make-Up Policy:**

To reduce the number of make-up quizzes, each student's grade will reflect the lowest quiz score and lowest homework score dropped.

** **

As stated earlier, for **emergency** situations, approval **MAY** be given for a missed class. At the discretion of the instructor, if the opportunity for a make-up quiz or test is given, this quiz or test will be more difficult than the scheduled quiz or test. If possible, students must meet with the instructor before missing a class to discuss the extreme circumstance. **If this is not possible, students must meet with the instructor prior to the next class meeting.**

**Plagiarism or Cheating** :

Serious consequences will occur in the event of plagiarism or cheating. Plagiarism occurs if you submit work of someone else or take credit for words of another. Cheating occurs if you use someone's work or allow another student to use your work. **In the event of sharing work, the integrity of both students is in question.**

** **

** **

*Violations of Academic Honesty*

* *

Submitting the work of another as your own--with or without his or her knowledge.

Stealing parts of or the entirety of a web site source, an article or a book for use in your paper.

Using the ideas and/or exact words of a professional writer (or internet source) without giving that person credit and without putting quotation marks around his or her words.

Sharing your paper with another student that he or she may use some or all of your ideas.

Submitting an essay in this class that has also been submitted in another class, or submitting an essay that contains a substantial amount of material taken from an essay submitted in another course.

** **

** **

**Important Dates:**

** **

** ** Last day to drop a class and receive full refund

Last day to withdraw with a W

**NOTE:** Following midterm, please know that it is your responsibility to withdraw from this class is you desire a W on your transcript. Failure to withdraw and not attending will result in an F for you transcript grade. Do not assume that I will withdraw you with a W for not attending.

- Calculate linear regressions based on given data.
- Use counting principals.
- Calculate basic probabilities using definition.
- Calculate probabilities using probability distributions, including Binomial and Normal Distributions.

**Security:**

** **

** ** Observe the campus maps in each room to locate fire exits, first aid kits, and evacuation meeting areas. Also discuss in each class the appropriate steps to follow in emergency situations. From any campus phone, dial 9 then 911. To reach security on campus, from any campus phone, dial 3199.

**Philosophy Statement:**

** **

Teaching is empowering students to achieve success both academically and personally. It is on one level guiding students to learn new material. However, on a deeper level, teaching is about giving students the ability to learn new ideas and build on these ideas. Students will see the positive effects of studying and working to achieve a goal through determination and dedication.

Students in my class will see a learning environment that is both exciting and challenging to promote excellence. Also, students will be treated with respect in a positive atmosphere where discussion of a variety of ideas is encouraged.

**A note of encouragement:**

** **

I look forward to working with you during this course. As with any math course, a dedication is needed toward both the completion of assignments and preparation for quizzes and exams. All odd-numbered problems have the answers in the back of the textbook. This is designed to give you a guide to understanding the concepts presented in each section. We will work several examples together during class; in addition, the text provides sample problems for you to study.

You need to know that this course will not be easy. If you have difficulty understanding a concept, please do not hesitate to ask questions during class; your questions will help the other students! You may also stop by my office, and I will be happy to answer your questions. There are videos and websites to assist your learning. Be sure to take advantage of the

Success Center where math tutoring is available. Please make an appointment in advance.

It is my goal that you will have a good experience with mathematics and leave this class with the confidence to pursue future mathematics courses.
