Answer 1

The association likely to have a negative correlation is the number of hours devoted to studying for a final exam and the final exam score.

Step-by-step explanation:

A negative correlation means that as one variable increases, the other variable decreases. Option (A) fits this criteria as the more hours a student spends studying for a final exam, the higher their final exam score is likely to be. Option (B) would likely have a positive correlation, with more years of teaching experience being associated with a higher salary. Option (C) would likely have a positive correlation, as older cars tend to have higher mileage. Option (D) would likely have a positive correlation, as larger families may spend more on their weekly food budget. Option (E) may or may not have a correlation, depending on the specific situation.

So, the correct answer is (A) Number of hours devoted to studying for a final exam and the final exam score.
