Question
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.
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=0.01
Weight, x

Setup the hypothesis for the test.
Identify the critical value.
Calculate the test statistic.
What is the conclusion? There is/is not enough evidence at the 1%level of significance to conclude that there is/is nota significant linear correlation between vehicle weight and variability in braking distance on a dry surface.
