E) The rejection region for this test would be t 3.250 so the null hypothesis would not be rejected. Decided weather to eject or fail to reject the null hypothesis using the P-value. Interpret the decision in the context of the original clam. Are the results the same as the critical value. ______ the results ______ the same as using critical value approach. ______ the null hypothesis. There ___ enough evidence to _____ this clam that the pass completion percentage have _____
