3 An article in Industrial Quality Control (1956, pp. 5-8) describes an experiment to investigate the effect of glass type and phosphor type on the brightness of a television tube. The response measured is the current necessary (in microamps) to obtain a specified brightness level. The data are shown in Table 13E.1. Completes the ANOVA table, and draw conclusion: whether the glass type, the Phosphor type, and their interaction have an effect on the brightness? Do NOT use minitab output the ANOVA table directly. However, you may use Excel to calculate the sum-of-squares. TABLE 13E.1 Data for Exercise 13.1.
