Final answer:
When the frequency of conversations with spouses decreases as age increases, it implies a negative correlation between these two variables.
Step-by-step explanation:
If people tend to have fewer conversations with their spouses as they age, then these two variables—age and the frequency of conversations with spouses—are negatively correlated. Negative correlation refers to a relationship between two variables in which one variable increases as the other decreases. In this particular example, as age goes up (increases), the frequency of conversations (decreases), indicating a negative correlation between the two variables.
