Question: In Exercises 9-12, find the equation of the regression line for the data. Then construct a scatter plot of the data and draw the regression line. (Each pair of variables has a significant correlation.) Then use the regression equation to predict the value of \(y\) for each of the \(x\) -values, if meaningful. If the \(x\) -value is not meaningful to predict the value of \(y\), explain why not. If convenient, use technology.
The amounts (in billions of pounds) of milk produced in the United States and the average prices
The engine displacements (in cubic inches) and the fuel efficiencies (in miles per gallon) of seven automobiles
| Displacement, X | Fuel efficiency, Y |
| 170 | 29.5 |
| 134 | 34.5 |
| 220 | 23 |
| 305 | 17 |
| 109 | 33.5 |
| 256 | 23 |
| 322 | 15.5 |
- x = 86 cubic inches
- x = 198 cubic inches
- x = 289 cubic inches
- x = 407 cubic inches
