An experiment was conducted to determine the effect of germination time (in days) and temperature (degrees C) on the free alpha amino nitrogen (FAN) content of rice malt. The values shown in the following are the treatment means of FAN with n = 2 (data from Aniche and Okafor 1989).
The total sum of squares was 8097. Draw an interaction plot for these data. Compute an ANOVA table and determine which terms are needed to describe the means.
