Based on prior knowledge, the marital status of an individual may be related to their income level. Let's analyze the relationship between the feature "marital-status" and the target "Does this person earn more than 50000 dollars per year?"

Possible hypothesis:

1. Married individuals may have higher incomes compared to never-married individuals.
2. Widowed, divorced, and separated individuals may have lower incomes compared to never-married and married individuals.
3. Individuals who are married to Armed Forces personnel (Married-AF-spouse) and individuals with their spouses absent (Married-spouse-absent) may have higher incomes.
4. The Widowed, Married-civ-spouse, and Divorced categories could have a mix of high and low income individuals.

Now let's generate the dictionary:

```json
{
	"no": ["Never-married", "Widowed", "Divorced", "Separated"],  
	"yes": ["Married-civ-spouse", "Married-spouse-absent", "Married-AF-spouse"]
}
```

In this dictionary, we have included the categories that are more likely to have individuals with incomes less than or equal to $50,000 in the "no" list, while the categories that are more likely to have individuals with incomes higher than $50,000 are included in the "yes" list.
