# MAT 1430 Syllabus

Catalog Course Description

To introduce statistical concepts and methods useful in analyzing problems in all areas of business and economics.  In addition to learning the concepts, applications will be addressed in: Descriptive Statistics, Discrete and Continuous Probability Distributions, Sampling Distributions, Confidence Intervals, Hypothesis Testing, and Regression Analysis.

Objectives

The purpose of this course is to provide the students with a sound conceptual and practical introduction to statistics and its applications in the business and economic fields.  Upon completion of the course, a student will be able:

• To recognize business situations that require the use of statistical tools of analysis.
• To select and execute the appropriate statistical tool for a specific business situation.
• To develop critical judgment and decision-making ability through the use of quantitative tools and statistical software.
• To address ethical issues when presenting and interpreting statistical information.
