I. Outline of the Course

 

Instructor: Hokwon A. Cho, Ph.D., Associate Professor, CBC B-506, Office phone: 895-0393 (Math. Sci. dept. office: 895-3567), E-mail: cho@unlv.nevada.edu.

Class Time and Location: M-F 2:40 p.m. - 4:10 p.m., CBC C-125.

Office Hours: MWF 10:30 a.m.-12:00 p.m., TR 1:30 p.m.-2:30 p.m., or by appointment.

Textbook: Probability & Statistics for Engineers & Scientists, by Walpole, Myers, Myers and Ye. 8th Ed., Prentice Hall.

Scope of the Course:

This is a calculus-based course in probability and statistics. The main goal of this course is to provide various statistical methodologies and their applications in data analysis. We will cover Chapter 1 through 10 in the text at minimum and some selected topics from chapters 11 if time permitted. Among topics to be covered will be

 

1.        Data, Graphical Descriptive Techniques - Measures of central Tendency and dispersion; numerical measures of relative standing; box plots, outliers, scatter-plots.

2.        Introduction to probability - Sample spaces, events, probability rules; conditional probability, independent events. Bayes theorem.

3.        Random variables and their distributions - Discrete random variables; probability, distributions, binomial and Poisson distributions, continuous probability distributions, Normal and exponential distributions, Joint probability distributions, Expectations of random variables.

4.        Sampling distributions - Sampling, law of large numbers, central limit theorem.

5.        Estimation - Point estimation, desirable properties, confidence interval for a population mean and a population proportion; sample size determination.

6.        Testing Statistical Hypotheses - test of hypothesis about a population mean: z-test; t-test, p-value; test of hypothesis about a population proportion, comparing two population means: independent sampling and paired t-test

 

Homework:

There will daily homework assignments and expected to complete them same day. Some of them will be collected for credit and quizzes will be given among the problems assigned.

Grading: The course grade is based upon the following:

(1) Homework or quizzes 20%, (2) Two tests 25% each (3) Final Exam 30%.

Letter grades: A (100-85%), B (84-75%), C (74-65%), D (64-55%) and F (54% and below).

Exams: Two exams are schedule on Thu. 14th  and Tue. 26th in June. The final exam is scheduled 2:40 p.m to 4:10 p.m on Friday, July 6.

Sizzling Summer Surviving Guide

 

(1)     Don’t be absent – attend every class. Classroom is cool!

(2)     Practice homework problems right after each class – do the assignments everyday.

(3)     Ask for help from the instructor or others immediately whenever you have questions or stuck.
