This is the life :)

So the project is over now!!! All of the students had to present their results on Friday. Everyone did very well. This is the link to the power point presentation. Also, I had to conduct t-tests. For more information on what a t-test is, you can go to this website. I have scanned all of my work for the t-tests. Basically, what the p value is the lowest alpha for which the hull hypothesis (H subscript 0) can be rejected. So the smaller the alpha, the harder it is to reject the null hypothesis. For many of alternate hypotheses that I conducted on the second sheet (on the right), the p value is very high. This means that it is okay to reject the null hypothesis because there is enough proof against it.
