#### Course Description

A study of the fundamental concepts and methods of probability and statistics. Topics include counting problems, discrete probability, random variables and probability distributions, sampling distributions, the central limit theorem, introduction to hypothesis testing.

#### Program Goals

1. Understand the fundamentals of probability theory.
2. Understand statistical and inferential reasoning.
3. Become proficient at statistical computing.
4. Become skilled in the description, interpretation and exploratory analysis of data by graphical and non graphical methods.

#### Course Objectives

1. Find Descriptive statistics and interpret the statistic in the context of the problem.
2. Use technology to vilualize continuous and categorical data.
3. Use counting techniques to compute probability and odds.
4. Calculate conditional probabilities and check for independent events.
5. Calculate probability for discrete random variable.
6. Calculate probability of continuous random variable.
7. Compute expected value and variance for different probability distribution.
8. Find a set of significantly contributing factors for the subject response variable.

#### Textbook

Introduction to Probability and Statistics , 14th Edition, William Mendenhall III, Robert J. Beaver, Barbara M. Beaver; ISBN-13:978-1-133-10375-2,Brooks/Cole. We will be covering chapters 1, 2, 3, 4, 6, 7, 8, and 9*. Apart from text book we will use different resources for the classroom activities and homeworks.

#### Homework

At least one set of homework problems will be assigned from each chapter using webassign . Some additional homework problems will periodically be assigned during the lecture. Good news! lowest homework grade will be dropped. You are expected to spend an average of 3-5 hours of work per week outside of class. Late assignment is accepted with 20% penalty per day. For better exam results you need to master all the homework problems.

#### Exams

There will be two mid-term exams, and a comprehensive final. To answer the exam questions, you are expected to have clear mathematical reasoning of the statistical methods used to solve the subject problem.

#### In Class Work and Quizzes

You will get worksheets with problems in the class. Students can interact with the friends and look at the notes to solve the problems. I encourage everyone to solve the problems on the white board and interpret the results to the class. I urge you to find interesting problems from the areas (eg. business, sociology, biology, sports, public health etc.) of your interest, this will help you to prepare for your project and at the same you are higly likely to earn better score in quizzes.

#### Project

There will be two mini-projects during the semester. For a good project, you need to describe the data, pose reasonable hypotheses, select appropriate statistical tests, compute the test results, and explain the results in both statistical terms and in plain English. Primary objective of these projects is to apply statistical methods in the real life situations and encourage students to work in a group. Late submission of project will result in losing 10% of total points everyday.

#### Software

We will use a software called "R". R is a programming language for statistical computing and visualizing data. It can be downloaded for free from http://www.r-project.org. We will use R Studio for regular classroom activities. R studio is an open source Integrated development Environment(IDE) for R. To download R click here for windows and here for Mac. After Installing R: click R Studio to download R studio.

Your performance is measured by the weighted average of homework, exams, project and classwork/quizzes. If you have any grade disputes you need to notify me within a week after grades are posted in canvas.
 Evaluations : Exam I (20%) Thursday, October 12 Exam II (20%) November, November 21 Online homework (15%) November, November 21 classwork (10%) TBD Group project part I (5%): Due October 31 Group project part II(5%): Due December 05 Final Exam (25): Tuesday, Dec 19(3:00 -6:00PM)

Grade Distribution

Your final grade will be based on two mid-term exams, a set of online graded homeworks, classwork, two mini-projects, and a comprehensive final exam. Lowest homework grade will be dropped. Your performance is measured by the weighted average of exams, homeworks, and projects. T The table below shows percentage intervals for the distribution of letter grades:
 Letter Grade E D- D D+ C- C C+ B- B B+ A- A A+ Percentage 0-59 60-62 63-66 67-69 70-72 73-76 77-79 80-82 83-86 87-89 90-92 93-96 97-100

#### Disability Statement

The University will make reasonable accommodations for persons with documented disabilities. Student need to register with Disability Resource Services (DSR) every semester they are enrolled for classes. DRS is located in counseling & Support Services, 2157 UC. To be assured of having services when they are needed, students should register no later than the end of add/ drop deadline of each term. Visit the DSR website at: webapps.umd.umich.edu/aim. If you have disability that necessitates an accommodation or adjustment to the academic requirements stated in this syllabus, you must register with DRS as directed above and notify me. Upon receipt of your notification, we will make accommodation as directed by DRS.

#### Academic Integrity

￼The University of Michigan-Dearborn values academic honesty and integrity. Each student has a responsibility to understand, accept, and comply with the University's standards of academic conduct as set forth by the Code of Academic Conduct ￼(mdearborn.edu/policies_st-rights), as well as policies established by each college. Cheating , collusion, misconduct, fabrication, and plagiarism are considered serious offenses, and may be monitored using tools including but not limited to TurnItIn. Violations can result in penalties up to and including expulsion from the University. At the instructor's direction, the penalty may be a grade zero on the assignment up to and including recommending that student be expelled from the University. It is the sole responsibility of the student to understand and follow academic guidelines regarding plagiarism. The University of Michigan-Dearborm has an online academic integrity tutorial that can be accessed at: umdearborn.edu/umemergencyalert
