The weights(in pounds) of 6 vehicles and the variability of their braking distances(in feet) when stopping on a dry surface are shown in the table. Can you conclude that there is a significant linear correlation between vehicle weight and variability in braking distance on a drysurface? (Use alpha) = 0.01.
