An automobile manufacturer is designing a new compact model with a displacement of 3.2 liters with the objective of creating a model that will achieve at least 24 estimated highway MPG. The manufacturer must now decide if the car can be designed to use premium fuel and still achieve the objective of 24 MPG on the highway. Use the model developed in part (e) to recommend a decision to this manufacturer. (Round your answers to one decimal place.) Using the estimated multiple linear regression equation developed in part (e), a new model that is designed to use regular fuel would have 90.6 Incorrect: Your answer is incorrect. MPG on the highway and a new model that is designed to use premium fuel would have 8.5 Incorrect: Your answer is incorrect. MPG on the highway. Therefore, the new model should be designed to use regular Correct: Your answer is correct. fuel
