For Module 2, you should read through the following material in this textbook. There is quite a bit of detailed material in this module, so please start early.

Chapter 7: The Central Limit TheoremSections 7.1 and 7.2 onlyThis chapter explains sampling distributions and the Central Limit Theorem.

Chapter 8: Confidence IntervalsSections 8.1, 8.2, and 8.3 onlyThis chapter explains how to calculate confidence intervals for population means and proportions.

Chapter 9: Hypothesis Testing with One SampleThis chapter introduces hypothesis testing, including the general steps and how to conduct one-sample tests.

Chapter 10: Hypothesis Testing with Two SamplesSections 10.1, 10.3, and 10.6 onlyThis chapter expands on Chapter 9 material and focuses on two-sample tests. There are five tests introduced in this chapter, but we will only focus on three of them.

Chapter 9 in the textbook for this module discusses hypothesis testing. Describe a hypothesis test that you would like to conduct. Be sure to include the following:

1. The null and alternate hypotheses (discussed in section 9.1 in the textbook).
2. Explain whether this test is a one-tail or two-tail test (section 9.3 in the textbook discusses the difference).
3. Describe the data you would need to collect to conduct the test.

Please remember to be specific and to put the discussion into your own words. Do not just copy and paste technical information from the textbook or another source. Really strive to understand how you could conduct this hypothesis test.

Week 1: Provide your initial discussion post to the question. Be sure to include references to any resources you used. You should use at least one resource to help you with your initial discussion.

Week 2: Respond to at least two of your classmates’ initial posts. Your response should be substantive and further the discussion. It is OK to be critical and use critical thinking. That means you can question what your classmates say. Do they provide their own critical thinking and logic?
