An experiment was run to determine whether four specific firingtemperatures affect the density of a certain type of brick. Acompletely randomize experiment led to the following data :

Temperature Density
100 21.8 21.9 21.7 21.6 21.7
125 21.7 21.4 21.5 21.4
150 21.9 21.8 21.8 21.6 21.5
175 21.9 21.7 21.8 21.4
Does the firing temperature affect the density of the bricks ?Use α = 0.05

Write 17/20 as a decimal and as a percent.
