In a bumper test, three test vehicles of each of three types of autos were crashed into a barrier at 5 mph, and the resulting damage was estimated. Crashes were from three angles: head-on, slanted, and rear-end. The results are shown below. Research questions: Is the mean repair cost affected by crash type and/or vehicle type? Are the observed effects (if any) large enough to be of practical importance (as opposed to statistical significance)? 5 mph Collision Damage (5) Crash Type Head-On Goliath Varmint 1,720 1,680 1,650 1,880 1,760 1,640 Weasel 2, 290 1,600 1,750 2,020 1,550 2,410 1,670 1,630 1,260 710 1,480 se0 Slant 1,410 1,750 1, 280 760 Rear-end 1, 280 930 1,550 1,260
