Question

Can it be determined from the ANOVA table whether there are differences in the measured weights among the operators? If so, provide the value of the test statistic and the P-value. If not. explain why not. It turned out that the measurements made by operator 13 were taken shortly after the balance had been powered up, while the others were taken after the balance had been powered up for some time. A new policy was then instituted to leave the balance powered up continuously. The three operators then made two weighings of three different wafers. The results are presented in the following table.
