A simple economic model predicts that a fall in the price of bus tickets means that more people will take the bus. However, you observe that some people still do not take the bus even after the price of a ticket fell. Part 2 Is the model incorrect? A.

Yes, because it does not predict the outcome with 100 percent accuracy. D. Yes, it's possible that certain factors, such as the price of gas, were not included in the model. Part 3 How would you test this model? A. You should run a natural experiment by analyzing bus ridership and price changes. B. You should randomly question people to see if they prefer taking the bus to other forms of transportation. C. You should determine whether increased bus ridership implies causation or correlation. D. All of the above are appropriate ways to test your model
