Question 1 Stopping Distances In a study on speed control, it was found that the main reasons for regulations were to make traffic flow more efficient and to minimize the risk of danger. An area that was focused on in the study was the distance required to completely stop a vehicle at various speeds. Use the following tables to answer the questions. MPH BRAKING DISTANCES (FEET) 20 20 30 45 40 81 50 133 60 205 80 411 Assume MPH is going to be used to predict stopping distance. Develop the regression equation for the sample. Can braking distance be accurately predicted from MPH? Estimate the breaking distance if a motor vehicle is travelling at 35 MPH and 76 MPH.
