2. Apply your knowledge about confidence intervals to Table 2, below. If the highlighted section were presented as inferential tests the null hypotheses would be H0: IRR=1. Please fill in the blanks for the following: (4 points) a. The significance level for these tests would be alpha=_________, ___________-sided. b.We would reject the null for _______________________________________________________. (e.g., Quartile 1, 2, 3, or 4) c. The p-value would be > 0.05 for _____________________________________________________. (e.g., Quartile 1, 2, 3, or 4) d. The role-type classification for these relationships is C->C (2x2). For Quartile 4, the exposure is ____________________________________, and the levels of that variable are ________________________________________ and ___________________________________________. e. The outcome is _______________________________________________________________ and the levels are ______________________________________ and ________________________________________
