|MA 222 - Probability & Statistics|
Introduces the essentials of probability theory and elementary statistics. Lectures and assignments greatly stress the manifold applications of probability and statistics to computer science, production management, quality control, and reliability. A statistical computer package is used throughout the course for teaching and for assignments. Contents include: descriptive statistics, pictorial and tabular methods, and measures of location and of variability; sample space and events, probability axioms, and counting techniques; conditional probability and independence, and Bayes' formula; discrete random variables, distribution functions and moments, and binomial and Poisson distributions; continuous random variables, densities and moments, normal, gamma, and exponential and Weibull distributions unions; distribution of the sum and average of random samples; the Central Limit Theorem; confidence intervals for the mean and the variance; hypothesis testing and p-values, and applications for the mean; simple linear regression, and estimation of and inference about the parameters; and correlation and prediction in a regression model.

A student completing this class is expected to understand probability reasoning. In addition he/she would have a good understanding of working with probability and have rudimentary notions of statistics. For an in-depth understanding of statistics the MA331 continues this class.
- Demonstrate an understanding of basic principles of probability, and sample spaces.
- Demonstrate understanding of conditional probability, independence and Bayes rule.
- Know the basic discrete distributions (Binomial, Geometric, Negative Binomial, Hypergeometric, and Poisson) and how to work with them.
- Know the basic continuous distributions (Uniform, Normal, Student t, Gamma and Beta) and know how to work with them
- Understand how to calculate fundamental concepts such as the cumulative distribution function, expectations, and distributions for functions of random variables.
- Know how to work with bivariate distributions and how to calculate basic two-variable statistics (covariance, correlation).
- Know the definition and be able to calculate the Characteristic function of a distribution; know how to apply the Central Limit Theorem.
- Know how to describe distributions using graphs and numerical descriptors.
- Understand basic methods of point estimation.
- Be able to evaluate estimators, construct confidence intervals, and perform hypothesis tests in the context of a single population sample.
