35. To compare the effects of five different assembly methods (denoted by the Latin letters A,B,C,D, and E ) on the throughput, an experiment based on a Graeco-Latin square was conducted which involved three blocking variables: day, operator, and machine type. The data are given in Table 3.50, where the machine type is denoted by the five Greek letters. The response, throughput, is the number of completed pieces per day and is given in the parentheses in the table. Analyze the data and compare the five assembly methods. Which of the methods are significantly better than the others
