In a study Durability of Rubber to Steel Adhesively Bonded Joints conducted at the Department, of Environmental Science and Mechanics and analyzed by the Statistics Consulting Center at the Virginia Polytechnic Institute: and Stale University, an experimenter measures the number of breakdowns in an adhesive seal. It was postulated that concentration of sea wafer A, temperature B, pH C, voltage D, and stress E influence the breakdown of an adhesive seal. A ? fraction of a 2" factorial experiment is used, with the defining contrast being ABCDE. The data are as follows. Perform an analysis of variance on main effects and two-factor interactions, assuming that all three-factor and higher interactions are negligible. Use eV =0.05.
