What is your​ conclusion?

There▼ enough evidence at the 5​%level of significance to conclude that there▼is a significant linear correlation between vehicle weight and variability in braking distance on a dry surface.

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 α= 0.01 Weight, x Variability in braking distance, y 囲Click here to view a table of critical values for Student's t-distribution. 59505380 6500 5100 5850 4800 ce, y | 1 74 1.991 187 L 162 1165 1.74 1.99 1.871.62 1.651.50
