An epoxy resin is being studied to improve hardening time. Two factors are being investigated and lower hardening time is desired. Factor A, Temperature, has three levels: Low, Medium and High. Factor B, the Amount of Hardener, has two level: Low and High. Three samples were collected for each combination and the hardening time was collected and is summarized in the table below: Temperature High Med Low 3.2 2.1 5.2 Low 3.1 2.5 5.1 Amount of Hardener 3.3 2.4 5 4.5 3.6 2.3 High 4.6 3.4 2.4 4.8 3.7 2.5 a. Perform Analysis of Variance on the data and determine the significance of Temperature, Amount of Hardener and their interaction. (a = 0.05) b. Graph the main effects and comment on the interaction it suggests. c. What combination of levels for Temperature and Amount of Hardener can be expected to produce the lowest hardening time?
