May 2, 2009 - Summary

Class Summary:

Topics covered continue the previous discussion on hypothesis testing presented in
Unit 8 in which we learn to test a claim about a population mean and the difference of
means between two populations.

We learned to identify when they can conduct a z-test or a t-test for large and
small sample sizes and make a decision based on testing results.
