3) Boeing 737 airplanes are often used for commercial flights. The airplane has two main landing gear and a single nose gear. Each gear is made up of a two-wheels, making up 6 wheels in total. The integrity of these wheels is very important since any serious problems with them could lead to catastrophic issues. A test is run at the parts producer (Collins Aerospace) located in Oakville, Ontario to determine the effect of four factors on the wheels. The four factors are temperature (A), rubber content (B), titanium alloy content (C), and assembly method (D). Two replicates of a 24 design are run and the integrity of the wheel (scale from 0 2.5) subjected to a standard test is measured. The data are shown in the table below: B D + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + + + + + + + + + + + + + + + + III Treatment Combination (1) a b ab bc abc d ad bd abd cd acd bcd abcd Replicate I II 1.71 2.01 1.42 1.58 1.35 1.63 1.67 1.65 1.23 1.48 1.25 1.36 1.46 1.52 1.29 1.37 2.04 2.29 1.86 1.95 1.79 2.05 1.42 1.69 1.81 2.02 1.34 1.39 1.46 1.63 0.85 1.00 + + + + + + + a.
