Suppose a statistician chose to test a hypothesis at a = 0.01. The critical value for a right-tailed test +2.33. If the test value were 1.97, what would the decision be? What would happen if, after seeing the test value, she decide to choose a = 0.05? What would the decision be? Explain the contradiction, if there is one.
