Air Fares Using Expedia, a discount travel website, the American Airline prices for a one-way flight from New York City to various cities were recorded. The following table gives the distances from New York City to 14 selected cities, along with the airfare to each of these cities.
City | Distance, x (miles) | Price, y (dollars) |
Chicago | 802 | 191 |
Denver | 1771 | 183 |
Kansas City | 1198 | 193 |
Little Rock | 1238 | 247 |
Los Angeles | 2786 | 316 |

- (a) Plot the data. Do the data points lie in a linear pattern?
- (b) Find the
correlation coefficient . Combining this with your answer to part (a), does the cost of a ticket tend to go up with the distance flown? - (c) Find the equation for the least squares line, and use it to find the approximate marginal cost per mile to fly.
- (d) Identify the outlier in the
scatterplot . Discuss the reason why there would be a difference in price to this city.
