Reasons for Modeling: Estimating Relationships

Another common application of modeling is to compare two data sets by building models for each, and then comparing the models. In this exercise, you are given data for a road trip two cars took together. The cars stopped for gas every 50 miles, but each car did not need to fill up the same amount, because the cars do not have the same fuel efficiency (MPG). Complete the function efficiency_model(miles, gallons) to estimate efficiency as average miles traveled per gallons of fuel consumed. Use the provided dictionaries car1 and car2, which both have keys car['miles'] and car['gallons'].

context figure

Complete the function definition for efficiency_model(miles, gallons).
Use the function to compute the efficiency of the provided cars (dicts car1, car2).
Store your answers as car1['mpg'] and car2['mpg'].
Complete the following logic statement to print which car (if either) has the best efficiency.
