An experiment was run to determine whether four specific firing temperatures affect the density of a certain type of brick. The experiment led to the following data.

(a) Does the firing temperature affect the density of the bricks? Use a = 0.05.
(b) Find the P-value for the F-statistic computed in part (a).
(c) Analyze the residuals from the experiment.

Temperature (CF) Density 21.8 21.9 21.7 21.6 21.7 21.5 21.7 21.4 21.5 21.5 21.9 21.8 21.8 21.6 21.5 21.7 100 125 21.8 150 21.8 21.7 21.6 21.8 175 21.9
