Based on prior knowledge, the number of hours-per-week an individual works can be a strong indicator of their income. Generally, working more hours-per-week tends to correlate with higher income. 

To analyze the relationship, we can consider the following:

- Individuals who work less than 40 hours-per-week might be more likely to earn less than $50,000 per year.
- Individuals who work exactly 40 hours-per-week could have varying income levels, so it is difficult to draw a conclusion based solely on this information.
- Individuals who work more than 40 hours-per-week are more likely to earn more than $50,000 per year.

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

```json
{
	"no": [20, 25, 30, 35, 37], 
	"yes": [45, 50, 55, 60, 65]
}
```

Please note that these are just example values and the actual range of hours-per-week values may vary.
