Temperature patterns seem to be changing around the United States. Winters seem shorter,
summers seem hotter, and major storms seem more frequent. Lets collect some data and look at
whats happening in your area.

CTE 9: In this project, you will compute confidence intervals. In particular, you will compute
confidence intervals for the same quantity measured at different times, and you will then
compare these intervals. The subject is temperature and the patterns e

Week 5 Statdisk Pointers
For the Week 5 Statdisk assignment one of the things that can be confusing is how to find the
number of students who gained weight their freshman year. You need to export the data to Excel
so that you can sort it to see how many g

You did a really nice job on this first CT Rob. It was organized in how each exercise was presented (which I
appreciate), and it was accurate. You did a thorough job describing the data and the interpretations were
insightful.

First before you get started, I cant stress enough how important it is to do problems such as this step
by step. The procedure is absolutely sequentialso you need to take it step by step, or you wont do it
properly and you will

Excellent job Robthis is laid out beautifully. You took a wrong turn to find the best
predictive value thoughsee below. It is always good to provide a nice concise summary
statement in problems such as this: The best predicted breaking distance for a 4,00

This analysis was excellent Rob -you did a really nice job on it. The progression of the analysis was
very systematic and carefully thought through.
