An experiment was conducted to determine if either firing temperature or furnace position affects the baked density of a carbon anode. The data are shown below: 

 

Suppose we assume that no interaction exists. Write down the statistical model. Conduct the analysis of variance and test hypotheses on the main effects. What conclusions can be drawn? Comment on the model's adequacy.
