Question

An engineer wants to determine how the weight of a gas-powered car, x, affects gas mileage, y. The accompanying data represent the weights of various domestic cars and their miles per gallon in the city for the most recent model year. Complete parts (a)

Find the least-squares regression line treating weight as the explanatory variable and miles per gallon as the response variable.

**Car Weight and Miles Per Gallon Data**

This table presents a dataset that examines the relationship between car weight and fuel efficiency, measured in miles per gallon (MPG). Below are the details of each entry:

| **Weight (pounds), x** | **Miles per Gallon, y** |
|------------------------|-------------------------|
| 3759 | 16 |
| 3907 | 15 |
| 2754 | 25 |
| 3515 | 20 |
| 3225 | 22 |
| 2881 | 22 |
| 3647 | 17 |
| 2674 | 24 |
| 3410 | 18 |
| 3893 | 18 |
| 3402 | 18 |

This data can be used to analyze and understand how the weight of a vehicle may affect its fuel efficiency. You might notice a trend where lighter cars generally have a higher MPG compared to heavier cars. This type of analysis is valuable for automotive design, helping manufacturers create more efficient vehicles.

For a more detailed exploration, consider plotting these values on a scatter plot to visualize the correlation between car weight and fuel efficiency. Additionally, statistical methods like linear regression could provide insights into the strength and nature of this relationship.
