Is nationality a risk factor for stomach cancer? You may use 2-by-2 tables and calculation of adds ratio to make your assessment 2. Is nationality assaciated with eating bacon? You may use 2-by-2 tables and calculation of adds ratio to make your assessment 3. Fill in the strata-specific (strata by nationality), and crude OR's for both studies 4. Calculate the M-H (Mantel-jasnssell OR's for each study 5. In study 1, is nationality a confaunder of the relationship between eating bacon and stomach cancer? Explain your answer. In study 2, is nationality a confounder of the relationship between eating bacon and stomach cancer? Explain your answer. 6. How was the data "fixed in Study 2 relative to Study 1, so that nationality wauld no longer be a confounder? Specifically, what association between two things was removed in Study 2 as compared to Study 1? Show that this association was, in fact, removed.
