MATH 3670 Probability and Statistics with Applications
Spring 2018
MW 4:30 - 5:45 Weber SST III room 1
Office Hours: MW 1:00 - 2:00, Skiles 133B
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,
8th or 9th ed., Thomson
The syllabus can be found here.
You can see how the class will develop on the
webpage
of the previous time I teached it.
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 9th and 8th editions of the book I will
indicate in square brackets the number relative to the 8th edition.
The final grade will be based on the following rules: 40%
final, 40%
midterms,20% HW. Curving will be done on the final result.
The first midterm is tentatively scheduled for Wednesday February 21 and the
second on Wednesday March 28.
