Mean and median

In this chapter, you'll be working with the food_consumption dataset from 2018 Food Carbon Footprint Index by nu3. The food_consumption dataset contains the number of kilograms of food consumed per person per year in each country, food category column food_category, the amount of consumption, and its carbon footprint (co2_emissions) measured in kilograms of carbon dioxide, or CO2.

dplyr is loaded for you and food_consumption is available.
