Here's your final reading assignment. Read **Section 6.2 **in your textbook (**omitting Section 6.2.4**) and answer the following questions by noon, Monday, April 16th. Be sure to login (using the link near the bottom of the sidebar) to the blog before leaving your answers in the comment section below.

- Conducting a two-sample t-test requires that the underlying populations for both samples are normal. What are two methods we've seen for checking this normality assumption?
- Suppose you recruit 10 Vanderbilt undergraduates at random to sample the coffee at Starbucks and Panera, rating each store's coffee on a scale of 1 to 5. The average of the differences in the 10 pairs of ratings is 0.7 in favor of Starbucks, with a standard deviation of 0.5. Is this sufficient evidence to conclude that all Vanderbilt students prefer Starbucks coffee to Panera coffee? (Assume that the underlying populations here are normal.)
- What's one question you have about the reading?
