Based on my prior knowledge and understanding of the relationship between age and earning more than 50000 dollars per year, I can analyze the relationship as follows:

In general, it is expected that individuals who are older may have accumulated more work experience and higher qualifications, which could potentially lead to higher earnings. However, it is also important to consider that younger individuals may be in the early stages of their careers and have potential for future earnings growth.

Considering this, I would expect that the age range for individuals earning more than 50000 dollars per year would be relatively broad, as earnings can vary significantly based on factors such as occupation, education, and experience level.

Here is the dictionary with the age ranges for the "no" and "yes" target classes:

```json
{
	"no": [17, 25, 30, 40, 50],
	"yes": [30, 35, 45, 55, 60]
}
```

Please note that these age values are just examples and may not accurately represent the actual relationship between age and earning more than 50000 dollars per year. A more comprehensive analysis using statistical techniques would be required to provide a more accurate assessment.
