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 77%. Colby decided to run a hypothesis test to determine if the mean score of his class was different than the mean score of the population. a = .05. What is the mean score of the population? What is the mean score of the sample? Is this test one-tailed or two-tailed? Why? What are the null and alternative hypotheses in this case? Let's pretend that p was calculated, and p = 0.09, should Colby reject or fail to reject the null hypothesis? Why? What should Colby's statement of conclusion be? (This circles back to what is being tested)
