Question:

For the data set of odometer readings and asking price of used cars described in Exercise 6, check the requirements for regression. Would it be appropriate to use the odometer reading to predict the asking price for these used cars? If so, predict the asking price for one of these cars that has 50,000 kilometres on the odometer (with 95% confidence).
