Background: The U.S. EPA rates every vehicle sold in the US for its gas mileage in city driving, on the open highway, and a combined city-highway rating. Ratings are in miles per gallon (mpg).
Answer:
5. What is the EPA combined mileage rating for the 2011 Bugatti Veyron?
Make Model Year Highway (mpg)
City (mpg) Combined (mpg)
Bugatti Veyron 2011 15 8 10

For each of the three situations (fish, hurricanes, and car mileages), how are the first and second questions different?
Which of the two questions provides the most insight into fish, hurricanes, and car mileages in general? (Why?)

Scientists and engineers make observations and collect data with a question in mind.
They collect data from more than one example – from as many examples as is feasible. When measuring many examples, scientists and engineers expect that the data they collect will vary.
When answering their question, they have to come to understand why the data vary.
Three important ideas:
