hint:

National Bearings manufactures bearings at plants located in Portland Oregon, Houston Texas, and Jacksonville Florida. To measure employee knowledge of Total Quality Management (TQM), six employees were randomly selected at each plant and tested. The test scores for these employees are given in DATA. Managers want to know if, on average, knowledge of TOM is equal across the 3 plants. Test equality of mean scores at ( = 0.05. The F value of 1.326 is the F critical value of 3.682, therefore reject the equality of means. Knowledge of TOM is not equal across the 3 plants. The F value of 6.349 is > the F critical value of 3.682, therefore reject the equality of means. Knowledge of TOM is not equal across the 3 plants.Ovservation Portland Houston Jacksonville 85 71 69 75 75 74 82 73 72 76 74 79 71 69 85 85 82 77
