Quiz?
I expect there will be a quiz this day, which will basically be a times MyOpenMath assignment with two questions:
 Compute mean and standard deviation from a short list of data points, and
 Compute proportions from a contingency table.

Homework
There is a one point, nine problem MyOpenMath assignment due on Thursday, September 24. Its main objective is to get you ready for the problems.

Wednesday, September 23
Today, I'll show you my approach to our practice midterm quiz problems on MyOpenMath. The computations are all simple arithmetic, combined with normal distribution references to our Normal calculator page.There are lots of tools that you can use for this but you do need to make sure that you're working at sufficient precision. I'll use this Colab notebook to show you how to get that precision.

Monday, 10/5  The tDistribution:
