Based on prior knowledge, the feature "hours-per-week" can be a good indicator of whether a person earns more than 50000 dollars per year or not. Typically, individuals who work more hours per week tend to have higher incomes.

To conduct a thorough analysis, we can consider the following:

1. Individuals who work fewer than 35 hours per week may have lower incomes.
2. Individuals who work between 35 and 40 hours per week may have moderate incomes.
3. Individuals who work between 40 and 45 hours per week may have higher incomes.
4. Individuals who work more than 45 hours per week may have even higher incomes.

Based on this analysis, let's create the dictionary:

```json
{
	"no": [20, 25, 30, 33, 35],
	"yes": [42, 45, 50, 55, 60]
}
```

Please note that these values are just examples and may vary based on the specific dataset being analyzed.
