Is displacement an appropriate predictor for the model? 101 + Displacement an appropriate predictor because the scatterplot shows MSRP (thousands) 5 - 300 600 DisplacementOff-road motorcycles (often called "dirt bikes") offer great variation in features. This makes them a good set to study to learn about which features account for the cost (manufacturer's suggested retail price, MSRP). Researchers collected data on model dirt bikes for a certain year. We are interested in using the data to predict MSRP from other variables. Scatterplots for three potential predictors are given. Comment on the appropriateness of using these variables as predictors on the basis of the scatterplots. Is wheelbase an appropriate predictor for the model? + Wheelbase an appropriate predictor because the scatterplot shows MSRP (thousands) 10-7 30 45 60 WheelbaseDisplacement Is bore an appropriate predictor for the model? Bore an appropriate predictor because the scatterplot shows MSRP (thousands) 5 - 30 70 110 Bore
