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: headcn, slanted, and rearend. The results are shown below. Research questions: Is the mean repair cost affected by crash type andr'or vehicle type? Are the observed effects [if any] large enough to be of practical importance [as opposed to statistical significance)? 5 rlph Collision Damage (5] Crash Type Goliath Varmint \"easel Head0n W30 1, 73% 2,259 1,430 1,579 1,619 336 1,636 1,786 Slant 1,416 1,856 2,656 1,?70 1,?59 1,599 1, 250 1, 539 2,449 Rear-end 1'30 850 1,636 1,2?0 1,516 1,516 94-0 1, 299 1,229 3 Click here forthe Excel Data File (II-1) Choose the correct roweffect hypotheses. a.
