Question: Refer to Data Set 15 in Appendix B and use the departure delay times and the arrival delay times. Find the best predicted arrival delay

Refer to Data Set 15 in Appendix B and use the departure delay times and the arrival delay times. Find the best predicted arrival delay time for a flight with no departure delay.
In each case, find the regression equation, letting the first variable be the predictor (x) variable. Find the indicated predicted values following the prediction procedure summarized in Figure.

Strategy for Predicting Values of y Is the regression equation a good model? The regression line graphed in the scatterplot shows that the line fits the points well . rindicates that there is a linear correlation. . The prediction is not much beyond the scope of the available sample data Yes. The regression equation is a good model No. The regression equation is not a good model. Substitute the given value of xinto the regression Regardless of the value of the best predicted value of y is the value of y (the mean of the yvalues) equation bothix
