  What is a test statistic and how is it related to a critical value in hypothesis testing? 3. What is the critical region in hypothesis testing and why is it important?

• Perform a hypothesis testing for one mean using t distribution

  Since the critical value from t distribution table is 1.86, we will reject null hypothesis if computed test statistic is larger than 1.86. 4. Compute the appropriate test statistic and make the decision.
