Critical value for a right-tailed test

Reference no: EM1397862

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