The Cochran's and Mantel-Haenszel statistics test the independence of Newspaper subscription and response, controlling for Income category. They report a significant relationship, with asymptotic significances less than 0.05. The Breslow-Day and Tarone's statistics test the homogeneity of the odds ratio across categories of the layer variable. The null hypothesis for these tests assumes that the odds ratio for Newspaper subscription by Response is equivalent for each value of Income category. The significance values are greater than 0.10, indicating that the odds ratio is in fact homogenous, which means that you should not use Income category to further target the mailings.
