OA. Reject Ho bècause the test statistic is greater than the critical value. O B. Do not reject H, because the test statistic is greater than the critical value. OC. Do not reject H, because the test statistic is less than or equal to the critical value. OD. Reject H, because the test statistic is less than or equal to the critical value.
