No. 607. Warnings : [1] Standard Errors assume that the covariance matrix of the errors is correctly specified. 1) The least squares regression line is: Y = 36. 0778 - 3. 5870X1 - 0. 0312X21. Review your peer's multiple regression model (#3 in their initial post). What is the predicted value of miles per gallon for a car that has 2.78 (2,780 lbs) weight and 225 horsepower? Suppose that this car achieves 18 miles per gallon, what is the residual based on this actual value and the value that is predicted using the regression equation
