MATH 3770 Statistics and Applications

Spring 2007

TR 3:05-4:35 Skiles 202

Professor Federico Bonetto

Office Hours: TR 4.30-5.30, Skiles 224.
Grader Name: Matt Schuchard
Grader Office Hours: TBA.

The course will introduce the basic notion of probability theory and its application to statistics. The focus will be on the discussion of applications.

The text that will be used is:

Jay L. Devore, Probability and Statistics, Thomson

The syllabus can be found here.

There will be two midterm.

The exercise listed are for HW collection. I will collect them every two weeks and grade 2 or 3 exercises among the one assigned. In case of differences between the 6th and 5th editions of the book I will indicate in square brackets the number relative to the 5th edition.

The final greade will be based on the following rules: 50% final, 35% midterms, 15% HW. Curving will be done on the final result.
