We will be using computers in the course, mostly in second semester. First semester we will only use the computers like a fancy calculator. In fact it could be replaced by some calculators for all the use we are going to make of it first semester, although most calculators, even expensive ones do not have all the probability distributions we want built in. Two that do are the Texas Instruments TI-83 and TI-83 Plus, but you probably don't want to buy such a calculator just for this course. If you have to buy a calculator, one that can do calculus like a TI-89 or a TI-92 Plus would perhaps be more helpful.

The default statistical computing package will be R, which can be used in the lab or downloaded (it's free software), and its web interface Rweb, which can be used in any web browser. If you are familiar with another computer statistics package, you may use that, but the instructor and teaching assistant may not be able to help you with it.

A recently added page explains using R and Rweb to calculate probabilites.

A recently added page illustrates the CLT using Rweb.

We are doing things in a bit different order this year.

What you should
look at as ``practice'' for this year's **first midterm**
(it isn't really,
the questions on this year's midterm may not all be on exactly the same
material) are questions 1, 3, and 4 on last year's
first midterm and question 1 on last year's
second midterm. Also you might use the density
in question 5 on last year's
first midterm changing the question from calculate
the conditional expectation (which we haven't done) to calculate the marginal
densities (which we have).

What you should
look at as ``practice'' for this year's **second midterm**
(it isn't really,
the questions on this year's midterm may not all be on exactly the same
material) are question 5 last year's first midterm,
questions 2, 3, and 5 on last year's second midterm,
and questions 4 and 7 on latst year's final exam.
