Question 3: An experiment was run to determine whether four specific fire temperatures affect the density of a certain type of brick. A completely randomized experiment led to the following data: a) Does the fire temperature affect the density of the bricks? Use at = 0.05%. b) Is it appropriate to compare the means using the Fisher LSD method (for example) in this experiment? c) Analyse the residuals from this experiment. Are the assumptions of analysis of variance satisfied
