QUESTION 9 (10 NL\RKS) An Automotive Association (AA) analysed the relationship between engine volume and mileage, given the same volume of petrol. Table 6 is tabulated for nine standard-transmission, four cylinders, petrol-fuelled cars from different car manufacturer. The engine volume is in total cubic kilometre (km). Table 6: Engine volume and mileage of different car manufacturer Car manufacturer Honda Datsun Chevrolet Proton Perodua Toyota Nissan Kia Based on the given data, Engine volume, x Mileage, y (cubic km) 97 85 98 105 120 151 134 146 (km) 24 29 26 22 23 23 21 i) ii) Find the least squares equation (i.e., linear regression) for the data Use the least-square equation to estimate the mileage for a car which has 125 cubic km engine volume.
