Problem 6

The Insurance Institute for Highway Safety conducts experiments in which cars are crashed into a fixed barrier at 40 mph. In a 40-mph offset test, 40% of the total width of each vehicle strikes a barrier on the driver side. The barriers deformable face is made of aluminum honeycomb, which makes the forces in the test similar to those involved in a frontal offset crash between two vehicles of the same weight, each going just less than 40 mph. Determine if the distribution of femur force in kilonewtons (kN) on the left leg resulting from this offset crash is the same for large family cars, passenger vans, and midsize utility vehicles at the a = 0.05 level of significance. The following data were collected from the study. Large Family Cars Femur Force (kN) Passenger Vans Femur Force (kN) Midsize Utility Vehicles Femur Force (kN) Chevrolet Lumina 5.8 Toyota Sienna 4.7 Mazda CX-7 1.0 Ford Taurus 1.9 Honda Odyssey 4.3 Toyota 4Runner 0.2 Buick LeSabre 2.8 Ford Windstar 2.1 Mitsubishi Montero 3.6 Chevrolet Impala 0.9 Mazda MPV 6.3 Nissan Xterra 1.8 Chrysler LHS 4.2 Chevrolet Astro 8.2 Ford Explorer 0.2 Pontiac Grand Prix 2.4 Nissan Quest 2.6 Jeep Grand Cherokee 2.3 Dodge Intrepid 4.7 Pontiac Trans Sport 6.7 Nissan Pathfinder 1.9 Source: Insurance Institute for Highway Safety
