31. Braking Distances Dry Surface The weights (in pounds) of eight vehicles and the variabilities of their braking distances (in feet) when stopping on a dry surface are shown in the table. At a = 0.01, is there enough evidence to conclude that there is a significant linear correlation between vehicle weight and variability in braking distance on a thy surface? fhvimat.
