Question:
In his book, D.C. Montgomery presents the results of an experiment involving a storage battery used in the launching mechanism of a shoulder-fired ground-to-air missile. Three material types can be used to make the battery plates. The objective is to design a battery that is relatively unaffected by the ambient temperature. The output response from the battery is effective life in hours. Three temperature levels are selected, and a factorial experiment with four replicates is run. The data are as follows:
a. Test the above hypotheses and draw conclusions using the analysis of variance with α = 0.05.
b. Analyze the residuals from this experiment.
c. Graphically analyze any interaction.
