1. What is the difference between a test of independent means and a test of matched means? 2. How would I calculate a test of matched means? what is the“matched” means? 3. Do you think both these tests ( a test of independent means and a test of matched means) are reasonable? Fair? Why or why not? Common concerns might be assumptions of the test being met, the practicality of the test, etc.
Suppose a test is performed to test H0: risk difference = 0 versus H1: risk difference ≠ 0, and the test rejects H0 at α = 0.05.
  Part 1. Suppose a test is performed to test H0: risk difference = 0 versus H1: risk difference ≠ 0, and the test rejects H0 at α = 0.05. Then, we can conclude that there is real significant evidence (α = 0.05) of a difference in proportions, _____________________ evidence that the risk difference is not 0, and _____________________ evidence that the relative risk and odds ratio are not _________________. Choose between significant, not significant, 0, 1. Part 2. Contrast...
