Statistics

In years past, we have used Michael Sullivan III's book titled Statistics, Informed Decisions Using Data, 2nd Edition as our text. This is the text used by Wytheville Community College math courses MTH 241 and MTH 242. All related material is preserved here for additional reference.

Statistics Chapter 10 discusses hypothesis testing. The lessons are Microsoft Powerpoint slides designed to be used in class with the student notes. They are a mixture of my own slides and information taken from slides supplied with the textbook. I have noted the file size beside them for those who still must use dial-up connections. Any suggestions or comments are always welcome.
