Question 03) An experiment was conducted to determine whether either firing temperature or furnace position affects the baked density of a carbon anode. The data are as follows:

Position	Temperature (C)
800	825	850
1	670	1043	565
565	1080	510
583	1043	590
2	518	978	526
547	1026	538
521	1004	532

a. Plot the interaction plot for this example.

b. Write the hypotheses for the main and interaction effects.

c. Use Anova to study the main effects of temperature and position in addition to the interaction effect. Report your Anova model.

d. Interpret your results. Are the main and interaction effects at a significant level of a =0.05?

e. Use pairwise comparisons to find which means are significantly different?

f. Utilizing the Q-Q plot and residual plots, check whether your model is adequate.
