Unformatted text preview: The absolute value of r = 0.0867286 is less than the critical value r = 0.3493697 Th ere is not a linear correlation between the weight and braking distance. If there is a linear correlation, then we input the necessary data into the prediction equation to find the best predicted value for braking distance for a vehicle weighing 4000 lbs. yhat = b0 + b1x If there is not a linear correlation, then we use the sample mean for y as the best predicted braking distance. You'll need to calculate that. 3. Just for practice, find the regression equation, letting the first variable be the predictor (x) variable. yhat = b0 + b1x Y = b0 + b1x y = 141.244 + 0.0012379*4000 y=141.244 + 4.9516 y=141.244  4.9516= 136.2924 y=136 .2924...
