The weights​ (in pounds) of 6 vehicles and the variability of their braking distances​ (in feet)...

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 dry​ surface? Use alphaα=0.05.

Weight, x   Variability in braking distance, y
5910 1.72
5390 1.99
6500 1.92
5100 1.63
5860 1.67
4800 1.50

The critical values are -2.776, 2.776

Calculate the test statistic.

Interpret this conclusion in the context of the original claim.
