A reseаrcher fits а multiple lineаr regressiоn mоdel tо predict a car’s fuel efficiency (measured in miles per gallon, mpg) based on horsepower (hp) and weight (wt, in 1000-lb units). The fitted regression output is shown below:Coefficients:(Intercept) 37.22727hp -0.03177wt -3.87783 (a) Write out the fitted regression equation for predicting mpg using hp and wt. (b) Using the fitted model from part (a), calculate the approximate predicted mpg for a car with hp = 150 and wt = 3.0 (i.e., 3000 lbs).
