2. Calculate the test statistic t= ? (Round to two decimal places)3. Calculate the P-value 4. What is your conclusion?_____ the null hypothesis. There _____ enough evidence at the 1% level of significance to conclude that there _______ a significant linear correlation between vehicle weight and variability in braking distance on a wet surface.

The weights (in pounds) of eight vehicles and the variabilities of their braking distances (in feet) when stopping on a wet 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 wet surface?
