### Assignments and Practice Problems

This course is an introduction to the mathematical theory of
probability and statistical inference. It focuses on the basic
theory and principles underlying statistical methods. Emphasis
will be placed on mastering concepts and techniques needed for
subsequent work in economics, econometrics, and other disciplines.
Students who complete 481/580 will be well prepared to study the
application of statistical methods in courses such as STAT
421/423/427, ECON 581/582, or other similar courses.
