Based on prior knowledge, education level can be a strong predictor of income. Generally, individuals with higher levels of education tend to earn more than those with lower levels of education. 

To analyze the relationship between education level and income more specifically, we can examine the distribution of education levels for individuals who earn more than 50000 dollars per year and those who earn less.

Based on this analysis, the dictionary would look like this:

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

In this dictionary, the values for the "no" key represent the potential education levels for individuals who earn less than or equal to 50000 dollars per year, while the values for the "yes" key represent the potential education levels for individuals who earn more than 50000 dollars per year.

It is important to note that this analysis is based on general assumptions and may not capture the full complexity of the relationship between education level and income.
