With the ever-increasing price of gasoline, both drivers and auto companies are motivated to raise the fuel efficiency of cars. There are many simple ways to increase fuel efficiency: Avoid rapid acceleration, avoid driving over 90 km/h, reduce idling, and reduce the vehicle’s weight. An extra 100 kilograms can reduce fuel efficiency by up to 2%. A marketing executive is studying the relationship between the fuel efficiency of cars (as measured in litres per 100 kilometres [L/100km]) and their weight to design a new compact car campaign. In the data set ch06_MCSP_Fuel_Efficiency_Canadian_Edition you’ll find data on the variables below:

• Model of Car

• Engine Size (L)

• MSRP (Manufacturer’s Suggested Retail Price in $)

• City (L/100 km)

• Highway (L/100 km)

• Weight (pounds)

• Type and Country of Manufacturer

Describe the relationship of weight, MSRP, and engine size with fuel efficiency (bothcity and highway) in a written report. Be sure to transform the variables if necessary.
