MATH 370 Syllabus

Probability and Statistics I

Revised: February, 2015

Course Description

Classical probability models, distributions of discrete and continuous random variables, joint probability distributions, mathematical expectation. Prerequisite: MATH 255. Three semester hours.

Student Learning Objectives

By the end of the semester, students will be able to

  • Model events occurring in nature in mathematical notation for future study.
  • Describe populations and predict events when only samples are available.
  • Interpret how industry uses statistical models in the design and production of goods and services.
  • Develop an appreciation for the use of mathematical concepts such as calculus in the development of statistics.
  • Understand the rather short history of statistics, its recent growth in applications, and current development.
