Context for question --banking officials claim that the mean bad debt ratio for all banks is 3.5 percent and that the mean bad debt ratio for Ohio banks is 4.225. The null and alternative hypotheses (Ho: mu <= 3.5% versus Ha: mu>3.5% ) is that the mean bad debt ratio for Ohio banks exceeds 3.5 percent. I need help with calculating the p-value for testing Ho versus Ha AND how to use the p-value to H0 versus Ha at each of a =.1, .05, .01, and .001
