Current Textbook

Mathematical Statistics with Applications, 7th edition. (2008), by Wackerly, D., Mendenhall, W., and Scheaffer, R.

Course Description

512—Mathematical Statistics (3) (Prereq: STAT 511 or MATH 511 with a grade of C or higher) Functions of random variables, order statistics, sampling distributions, central limit theorem, quality of estimators, interval estimation, sufficient statistics, minimum-variance unbiased estimator, maximum likelihood, large-sample theory, introduction to hypothesis testing.

Purpose:

To provide a strong foundation in mathematical statistics for understanding the concepts and development of statistical methodology, and to prepare students for further study of statistical inference.

Course Notes

You are encouraged to print out these notes ahead of time and bring them to class.

Homework

Note: Problems in the first column will be graded on effort and correctness (1 point for making a decent effort at the problem, 1 point for a correct (or very nearly correct) solution).
Problems in the second column will be graded on effort (1 point for making a decent effort at the problem) and not for correctness,
but you should try to understand how to solve all these problems before test time!

You must write your homework solutions NEATLY. You must present your solutions in the order that the problems are assigned (with the Column 2 problems last).
Handwritten solutions are fine, but if you type solutions, you should use either LaTeX or MS Word's Equation Editor,
since other word processors (like Word without Equation Editor) are not designed for mathematical typing.

NOTE: It appears that a few of the problem numbers in the "International Edition" of the textbook are switched around from the regular edition.
If you have the international edition, you might want to compare problem numbers with me or with a classmate who has the regular edition to make sure you're doing the problems assigned.
The problem numbers given above reflect the regular 7th edition.

Homework Solutions

Some Additional Practice Problems

These problems may be useful problems for practicing the Sec. 6.7 material on Test 1:
6.73, 6.77(a), 6.81 (answers to these are in the back of the book)

These problems may be useful problems for practicing the Sec. 9.8 material and the Sec. 7.5 material:
9.98, 9.99, 9.100, 7.81, 7.82

In general, I recommend that you practice lots of problems from the book in preparation for the tests!
