Based on prior knowledge, I would assume that a fasting blood sugar level greater than 120 mg/dl may indicate a higher likelihood of heart disease. Therefore, I will consider FastingBS > 120 mg/dl to be a positive indication (target class 'yes') for heart disease, and FastingBS <= 120 mg/dl to be a negative indication (target class 'no') for heart disease.

Using this information, I will analyze the relationship between the feature 'FastingBS' and the task of determining whether the coronary angiography of the patient shows a heart disease.

Dictionary:

```json
{
    "no": [85, 90, 95, 100, 110.5],
    "yes": [121, 126, 133, 140, 150.5]
}
```

Explanation:

The values in the list for the target class 'no' represent typical fasting blood sugar values (FastingBS) for patients whose coronary angiography does not show heart disease.

The values in the list for the target class 'yes' represent typical fasting blood sugar values (FastingBS) for patients whose coronary angiography shows heart disease.

Please note that these values are hypothetical and the specific values would depend on the available data and actual analysis.
