Based on prior knowledge, the relationship between the "educational-num" feature and the task of determining whether a person earns more than 50000 dollars per year can be analyzed as follows:

The "educational-num" feature represents the highest level of education achieved in numerical form. Generally, higher levels of education tend to correlate with higher incomes. Therefore, it is expected that individuals with higher educational-num values would be more likely to earn more than 50000 dollars per year.

To create the dictionary with the specified format, I will select 5 typical educational-num values for each target class ('no' and 'yes'):

```json
{
	"no": [1, 2, 3, 4, 5],
	"yes": [10, 11, 12, 13, 14]
}
```

Please note that these values are just examples and may not be representative of the actual dataset. The educational-num values 1 to 5 represent lower levels of education (e.g., elementary school, middle school, high school), while the values 10 to 14 represent higher levels of education (e.g., some college, associate's degree, bachelor's degree or higher).
