Based on prior knowledge, the feature "fnlwgt" represents the number of units in the target population that the responding unit represents. It is a numeric variable and can be used to determine whether a person earns more than $50,000 per year.

To analyze the relationship between "fnlwgt" and the target variable, we can compare the distribution of fnlwgt values for the target classes "yes" (person earns more than $50,000 per year) and "no" (person earns less than or equal to $50,000 per year).

Here is the dictionary containing the specified details:

```json
{
	"no": [135890, 122042, 184640, 149158, 223246],
	"yes": [35553, 275592, 120525, 176385, 237814]
}
```

These are 5 typical examples of "fnlwgt" values for each target class. The "no" class represents people who earn less than or equal to $50,000 per year, while the "yes" class represents people who earn more than $50,000 per year. The "fnlwgt" values are presented as integers in the lists.
