2. (40 points) An article in the Journal of Agricultural Engineering Research (1992, Vol. 52, pp. 53-76) described an experiment to investigate the effect of drying temperature of wheat grain on baking quality bread. Three temperature levels were used, and the response variable measured was the volume of the loaf of bread produced. The data are as follows: Temperature (°C) Volume (CC) 70.0 1245 1235 1285 1245 1235 1220 1210 75.0 1235 1240 1200 80.0 1225 1200 1170 1155 1095 (a) Does drying temperature affect mean bread volume? Use a 0.05. (b) Find the P-value for this test. (e) Use the Fisher LSD method to determine which means are different (d) Analyze the residuals from this experiment and comment on model adequacy.
