Based on prior knowledge, there is a strong relationship between education level and income. Generally, individuals with higher education levels tend to earn more than those with lower education levels. Therefore, it is likely that individuals with a higher education level will have a higher chance of earning more than $50,000 per year.

Based on this analysis, the dictionary will include the possible values of the education feature for both target classes:

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

In this case, individuals with education levels such as "11th", "HS-grad", "9th", "7th-8th", "10th", "5th-6th", "1st-4th", "Preschool", and "12th" are more likely to earn less than $50,000 per year. On the other hand, individuals with education levels such as "Assoc-acdm", "Some-college", "Prof-school", "Bachelors", "Masters", "Doctorate", and "Assoc-voc" are more likely to earn more than $50,000 per year.
