Answer: There is no association between the pounds of fruit purchased and the pounds of vegetables purchased.
Explanation:
If we go through the answers step by step, we can try sorting out the best fit:
Option 1 doesn't work because there are some cases where the fruit purchased increases, but the pounds of vegetables didn't increase.
Option 2 also doesn't because again, there are some cases where fruit purchased increased, and the pounds of vegetables didn't decrease.
Option 4 also doesn't work because there are cases where the amount of fruit bought is not the same as the pounds of vegetables bought.
Thus, leading to the final answer, Option 3.
