2. An experiment was conducted to determine whether four firing temperatures affect the density of brick. The experiment led to the following information Temperature 100 125 150 175 200 Total Grand Mean No. of Bricks (Reps) 3 4 4 3 4 18 Total Density 65.4 86.0 87.1 65.2 86.1 389.8 Mean Density 21.80 21.50 21.78 21.73 21.52 108.33 21.67 density-8441.82 a. At a -0.05, test whether the mean density of five firing temperatures are significantly different.
