Based on the given feature description, the feature "fnlwgt" represents the number of units in the target population that the responding unit represents. To determine the relationship between this feature and the task of whether a person earns more than 50000 dollars per year, we can analyze the distribution of the "fnlwgt" values for each target class.

Here's the generated dictionary with the possible values of the "fnlwgt" feature for the target classes 'no' and 'yes':

```json
{
	"no": [1000, 2000, 3000, 4000, 5000],
	"yes": [80000, 90000, 100000, 110000, 120000]
}
```

The values provided are just examples and are not necessarily the actual values from the dataset. The actual values may vary based on the specific dataset being analyzed.
