Final answer:
Increased alcohol consumption correlates with decreased driving ability, representing a negative correlation significant for public safety.
Step-by-step explanation:
As people consume more alcohol, their driving ability gets worse. This is an example of a negative correlation. In negative correlation, one variable increases while the other decreases. In this case, as alcohol consumption (one variable) increases, driving ability (the second variable) decreases.
This sort of relationship is significant in terms of public safety, as impaired driving can lead to increased accident rates. It's important to note that a negative correlation is different from no correlation, where changes in one variable do not predict changes in another.
