If, in a (two-tail) hypothesis test, the p-value is 0.1626, what is your statistical decision if you test the null hypothesis at the 0.08 level of significance? Choose the correct answer below? OA. Since the p-value is less than a, do not reject Ho OB. Since the p-value is greater than a, reject Ho- OC. Since the p-value is greater than a, do not reject Ho- OD. Since the p-value is less than a, reject Ho you want to be 95% confident of estimating the population mean to within a sampling error of 5 and the standard deviation is assumed to be 19, what sample size is required? The sample size required is (Round up to the nearest integer.)
