Professor Nord stated that the mean score on the final exam from all the years he has been teaching is a 79%.  Colby was in his most recent class, and his class’s mean score on the final exam was 82%.  Colby decided to run a hypothesis test to determine if the mean score of his class was significantly greater than the mean score of the population.  α = .01.

• What is the null hypothesis in this case?


• If p = 0.29, should Colby reject or fail to reject the null hypothesis?


• What should Colby’s statement of conclusion be?  (This circles back to what is being tested).
