Based on prior knowledge, we can assume that age can have an impact on a person's income. Generally, younger individuals may have lower income levels as they are starting their careers, while older individuals may have higher income levels due to more experience and seniority. 

To analyze the relationship between age and income, we can consider the following age ranges:

- 16-25: Younger individuals who are likely to have lower income levels.
- 26-35: Adults who have started their careers and may have moderate income levels.
- 36-45: Individuals in their prime working years, who may have higher income levels.
- 46-55: Experienced professionals who may be earning higher incomes.
- 56 and above: Older individuals who may be at the peak of their careers and potentially have high incomes.

Using these age ranges, we can create a dictionary as follows:

```json
{
	"no": [16, 17, 18, 19, 20], 
	"yes": [36, 40, 45, 50, 55]
}
```

Please note that these age values are representative examples and may not cover the entire range of possible values for each target class.
