Chapter 13, Problem 57SE

(choose chapter or problem)

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:

(a) Does drying temperature affect mean bread volume? Use \(\alpha=0.01\).

(b) Find the \(P-\text { value }\)  for this test.

(c) Use the Fisher LSD method to determine which means are different.

(d) Analyze the residuals from this experiment and comment on model adequacy.
