**Prerequisites & Bulletin Description**

## Course Objectives

This course provides a thorough background in the mathematics of probability and statistics including the use of standard statistical computer packages such as SAS, SPSS, MINITAB and/or some computer programming. It covers basic combinatorics, descriptive statistics including graphical treatments and numerical summaries of data, the axioms and theorems of probability theory, discrete and continuous probability functions and inferential statistics including estimation and hypothesis tests for one- and two- sample problems. This course is primarily designed for Computer Science and engineering majors. The students will learn to do data presentation with tables, graphs and calculation such as mean, media, standard deviation. They will be able to use probability and distribution theory for many of their applications in various fields of science in particular in Computer Science and Engineering. The teaching of estimation and testing will enable the students to analyze data and make correct statistical conclusion.

## Evaluation of Students

Instructors' assessment is usually based on homework, quizzes, computer assignments, in-class exams and an in-class final.
