Question - CO2 emissions in vehicles.
Natural Resources Canada tests new vehicles each year and reports several variables related to fuel consumption for vehicles in different classes. For 2015, it provides data for 526 vehicles that use regular fuel. Two variables reported are carbon dioxide (CO2) emissions and highway fuel consumption. CO2 is measured in grants per kilometer (g/km), and highway fuel consumption measured in liters per 100 kilometers (L/km). Use graphical and numerical summaries to describe the distribution of CO2 emissions for these vehicles. Be sure to justify your choice of summaries.
