Making Predictions Using the Model Make predictions using the regression model. Address the following questions in your analysis: What is the predicted fuel efficiency (miles per gallon) for a car that has a rear axle ratio of 3.15 and a horsepower of 120? Suppose that this car achieves an average of 20.5 miles per gallon. What is the residual for this observation? What is the 95% prediction interval for the car identified in the previous question? Interpret this interval. What is the 95% confidence interval for the car identified in the previous question? Interpret this interval. Why is the prediction interval wider than the confidence interval?
