10.1 ANOVA: The Completely Randomized Design

Glue Strength: Four adhesives that are used to fix porcelain to teeth are tested in a completely randomized design. The experiment bonds porcelain to teeth and then a machine is used to pry the tooth from the porcelain. The amount of force needed to do this for each bond is recorded. Use the results below and a 1% significance level to construct an ANOVA table to test the claim that there is a significant difference between the bonding strengths.
