Week 11 (3/30 to 4/5) 
The focus of this week is on Chapter 8: Hypothesis Testing sections 4 and 6, and plus section 3 of Chapter 9. The goals are to review the basic concepts of statistical hypothesis testing with special focus on testing the proportion of a population or a distribution. This week, you will study section 4 in chapter 8. (Do not worry about section 5.) During this week you will learn how to test the statistical hypothesis of a proportion of a population using zdistribution. So the test is a ztest. Please also use this week to review the concept of hypothesis testing for mean. It is very similar to the test of proportion. The concepts of hypothesis testing in this chapter is essential for learning all other test procedures that you may learn in the future. Section 6 of Chapter 8 explains the idea of using confidence interval estimate for testing statistical hypothesis for mean. Section 3 of Chapter 9, is an application of the ttest for testing the average (or mean) of the paired differences which is a very useful test often used in prepost study.To Do List:1.
