Based on prior knowledge, it is generally expected that individuals who work more hours per week have a higher likelihood of earning more than $50,000 per year. However, this relationship is not always true as there can be various factors affecting a person's income.

Here is the analysis of the relationship:

For the 'no' class (earning less than or equal to $50,000 per year):

1. Typically, individuals working part-time or less than 40 hours per week are more likely to earn below the threshold.
2. Many jobs that pay less than $50,000 per year are often part-time or have reduced hours.
3. Individuals with irregular or fluctuating work hours may earn less than $50,000 per year.
4. Some low-paying, entry-level jobs might have a limit on maximum hours per week to prevent employees from reaching the higher income threshold.
5. Individuals who choose to work fewer hours or have constraints on their availability might earn below $50,000 per year.

For the 'yes' class (earning more than $50,000 per year):

1. Typically, individuals working full-time or more than 40 hours per week have a higher chance of earning above the threshold.
2. Many high-paying jobs require long working hours to achieve higher income.
3. Professionals, executives, or highly skilled individuals often work more hours to reach higher income levels.
4. Self-employed professionals or entrepreneurs can work longer hours to earn higher income.
5. Individuals who have advanced in their careers and reached higher income levels tend to work more hours voluntarily.

Based on this analysis, here is the dictionary:

```json
{
	"no": [10, 20, 30, 35, 39],
	"yes": [45, 50, 55, 60, 65]
}
```
