Reference no: EM132833376

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 mean score of the population?
  • What is the mean score of the sample?
  • Is this test one-tailed or two-tailed? Why?
  • 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).
