The linear correlation coefficient between the weight of a car and its miles per gallon is $-0.945$, indicating a strong negative correlation. This suggests that as the weight of the car increases, the miles per gallon generally decrease.

Would you like further details or have any questions?

Here are some related questions for further exploration:

1. How is the strength of a correlation interpreted based on the correlation coefficient?
2. What factors might explain the negative correlation between weight and fuel efficiency?
3. Can we use this correlation to make predictions about other cars’ fuel efficiency based on their weight?
4. What is the importance of examining the correlation before making decisions in vehicle design?
5. How would removing one of the outlier data points affect the correlation coefficient?

Tip: Remember, correlation does not imply causation—it only measures the relationship, not the reason one variable affects the other.
