An article in Industrial Quality Control (1956, pp. 58) describes an experiment to investigate the effect of two factors (glass type and phosphor type) on the brightness of a television tube. The response variable measured is the current (in microamps) necessary to obtain a specified brightness level. The data are shown in the following table: (a) State the hypotheses of interest in this experiment. (b) Test the above hypotheses and draw conclusions using the analysis of variance with 0.05.
