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 (n=20). 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
