Here's your next reading assignment. Read Sections 4.3.4-4.4 in your textbook and answer the following questions by 8 a.m., Wednesday, March 14th. (Yes, that's Pi Day. No, I don't think that's the coolest thing ever.) 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.
- Consider the hypothesis test H0: μ = 100 vs. HA: μ < 100. Suppose the p-value for this test using a particular sample turns out to be p=0.04. What probability does this p-value represent? Be as specific as possible.
- Example 4.38 on page 167 provides a justification for the advice to never change a two-sided test to a one-sided test after observing the data. Do you accept this justification? Why or why not?
- In the example discussed in class on Monday, the hypothesis test H0: μ = 494 vs. HA: μ > 494 was conducted and found to have a p-value of p=.2743. Under what conditions would you be okay to reject the null hypothesis given this p-value?
- What's one question you have about the reading?
