Based on prior knowledge, higher levels of education are generally associated with higher income levels. Therefore, it is likely that individuals with higher levels of education will earn more than $50,000 per year compared to those with lower levels of education.

To create the dictionary, I will need to analyze the relationship between education and the task of earning more than $50,000 per year. I will examine the data and identify the different education levels that are associated with each target class.

Here is the dictionary based on the analysis:

```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 education levels that are associated with the target class "no" (earning less than or equal to $50,000 per year) are "11th", "HS-grad", "10th", "7th-8th", "9th", "12th", "1st-4th", and "Preschool".

The education levels that are associated with the target class "yes" (earning more than $50,000 per year) are "Assoc-acdm", "Some-college", "Prof-school", "Bachelors", "Masters", "Doctorate", "5th-6th", and "Assoc-voc".

Note: This analysis is based on the assumption that higher education levels are generally associated with higher income levels.
