Customers with these vehicles are suffering substantialdamage and repair costs in low-speed impacts to the bumpers. The company has been solicitingproposals for a new collapsible bumper system to upgrade the performance of their sedans to beequal to the industry average of $400 or less in a collision impact of ≤15 miles per hour (mph).Gruman Engineers believe they have found a bumper system that will meet this requirement. Todemonstrate it, they crashed six sedans with this bumper into a barrier at 15 mph, submitted themfor repairs and recorded the cost of the repairs. The mean and standard deviation of the costs arefound to be $458 and $48, respectively.
