3. See Lecture 1 notes (on page 38), for a new car model with city mpg = 30, the forecasted carbon footprint is y = 5.9 tons of CO2/year. Compute the corresponding forecasting intervals using the formula given on page 38.o Forecasts from a simple regression model for a specific "new" x: )7 = 30 + 31X- . The prediction interval for this forecast is Vila/256 1 +1+ o The estimated regression line for the car example is 57 = 12.53 0.22x. o For a new car model with city mpg=30, the forecasted carbon footprint is j? = 5.9 tons of C02/year. We can also compute the corresponding forecasting intervals. H t'xnr\
