Based on prior knowledge, the feature "hours-per-week" can be considered a relevant factor in determining whether a person earns more than $50000 per year. Typically, individuals who work more hours are more likely to have higher incomes.

To analyze the relationship between the "hours-per-week" feature and the task, we can observe the data and compare the distribution of hours worked for each target class.

Let's create a dictionary with the typical values of "hours-per-week" for each target class:

```json
{
    "no": [30, 35, 40, 45, 50],
    "yes": [40, 45, 50, 55, 60]
}
```

The values provided in the "no" list represent typical hours worked per week for individuals earning less than or equal to $50000 per year. Whereas, the values in the "yes" list represent typical hours worked per week for individuals earning more than $50000 per year.

Please note that these values are based on general assumptions and may not hold true for every individual or situation. It's always recommended to thoroughly analyze the data and consider other relevant factors as well.
