Week 10 (3/23 to 3/29)

The focus of this week is on Chapter 8: Hypothesis Testing. The goals are to learn the basic concepts of statistical hypothesis testing with special focus on testing the mean of a population or a distribution. This week, you will study sections 1 through 4 in this chapter. You will learn how to test the statistical hypothesis of a mean of a population using z- or t-distribution. It is a very important chapter on statistical inference. The concepts of hypothesis testing in this chapter is essential for learning all other test procedures that you may learn in the future. Just as the confidence interval estimation, t-test is a practical test procedure that is often used for testing mean of a population. It can be used for small sample from normal population or on a large sample. t-test is a very useful test procedure for statistical inference. Be sure to do as many exercise problems as possible.
