Based on prior knowledge, education level is expected to have a strong relationship with the income level. Generally, a higher level of education indicates more knowledge and skills, which increases the likelihood of earning a higher income. Therefore, it is likely that individuals with higher education levels will earn more than 50000 dollars per year.

To analyze the relationship between education and the income level, we can examine the distribution of education levels for each income class.

Here is the dictionary representing the relationship between education and earning more than 50000 dollars per year:

```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 the "no" class, we include education levels that are generally associated with lower income earners. These include categories such as 11th grade, high school graduate, 10th grade, 7th-8th grade, 9th grade, 12th grade, 1st-4th grade, and preschool.

In the "yes" class, we include education levels that are generally associated with higher income earners. These include categories such as Associate of Arts degree, some college education, professional school degree, bachelor's degree, master's degree, doctorate degree, 5th-6th grade, and associate of vocational education.

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