This course builds on the calculus-based treatment of probability provided in
STA341 to introduce concepts in statistics. After studying additional topics in
probability (including Chebyshev's inequality and convergence in probability),
students study descriptive statistics; point estimation including unbiased,
maximum likelihood, method of moments, efficient and minimum variance estimators;
confidence intervals; tests of hypotheses, significance testing with p-values,
goodness-of-fit tests; analysis of variance; and nonparametric methods.
GENERAL COURSE GOALS
To have students:
- expand their understanding of the nature of mathematical statistics
- improve their mathematical problem-solving skills, including their skill in presenting rigorous mathematical arguments in proofs and derivations
- learn to use mathematical statistics to gain insight into areas of application, for example in the physical and life sciences, and economics
- appreciate the importance of statistics in human civilization
- learn the appropriate use of technology including how to use it and when to be skeptical of its results
- develop critical thinking and a basic understanding of logic essential for lifelong learning

GENERAL REMARKS AND ADVICE
This web site is designed to, among other things, make it clear what is expected from you and what you can expect from the
course and from me. This course will be challenging; it is fast-paced, it requires a great deal of meticulous attention to detail as well as imagination and creativity, and just about everything in it depends
on your understanding of everything else in the course that preceded it. Nevertheless, if you work hard,
do not allow yourself to fall behind, and seek help when you need it, you should be successful in this course.
Reading assignments and homework problems for nearly each class meeting are posted on the course web site.
It is your responsibility to check the web site frequently (i.e., at least once a day) for the homework.
It is extremely important that you complete the reading assignments and try the homework problems before the following class meeting.
