An experiment was run to determine whether four specific firing temperatures affect the density of a certain type of brick. A completely randomized experiment led to the following data:Temperature Density100 21.8 21.9 21.7 21.6 21.7125 21.7 21.4 21.5 21.4 150 21.9 21.8 21.8 21.6 21.5175 21.9 21.7 21.8 21.4 a) Does the firing temperature affect the density of the bricks ?Use α = 0.05
