2. An experiment is done to investigate the impact of glass type and phosphor type on the brightness of a television tube. The current (in microamps) required to achieve a given brightness level is the response variable measured. The information is presented in the table below: Glass Type Phosphor Type 1 2 3 1 281 301 291 291 311 296 286 286 291 2 231 261 221 241 236 236 226 241 231 a. In this experiment, state the hypotheses that are of interest. b. Using the analysis of variance, test the above hypotheses and draw conclusions with a = 0.05.
