Unformatted text preview: Does the linear correlation for the data support a linear correlation? The absolute value of r = ___(fill in) is greater than/ is less than (choose one of these statements) the critical value r = __(fill in): There is a linear correlation / there is not a linear correlation (choose one of these decisions) 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...
