For the following test statistics that were obtained in Step 3 of the Hypothesis test, state whether the score falls in the critical region or not. Note that for these problems we MUST give the critical value used to make a decision in the appropriate column. No calculations are needed for this question. I need to demonstrate that I know how to use the tables and understand how to make a correct decision. Critical value from the appropriate table and whether to reject or retain the null are what I need help with.
