Based on prior knowledge, education level is likely to be correlated with income. Generally, a higher level of education is associated with higher income levels. Therefore, individuals with higher education levels are more likely to earn more than $50,000 per year compared to those with lower education levels.

Here is the dictionary with the relationship between education level and income:

```json
{
    "no": ["10th", "11th", "7th-8th", "9th", "12th", "1st-4th", "Preschool"], 
    "yes": ["HS-grad", "Some-college", "Assoc-acdm", "Bachelors", "Masters", "Prof-school", "Doctorate", "5th-6th", "Assoc-voc"]
}
```

The "no" list includes education categories that are less likely to result in earning more than $50,000 per year, while the "yes" list includes education categories that are more likely to result in higher income levels.
