Based on prior knowledge, a fasting blood sugar (FastingBS) level below 120 mg/dl is considered normal, while a level above 120 mg/dl is considered high. 

To analyze the relationship between FastingBS and the presence of heart disease as determined by coronary angiography, we can examine the values of FastingBS for each target class ('no' and 'yes'). For the 'no' class, we expect to see lower FastingBS values, indicating normal blood sugar levels in patients with no heart disease. For the 'yes' class, we expect to see higher FastingBS values, indicating elevated blood sugar levels in patients with heart disease.

Based on this analysis, we can create a dictionary with the typical FastingBS values for each target class.

```json
{
	"no": [110.0, 115.0, 116.0, 118.0, 119.0],
	"yes": [125.0, 130.0, 135.0, 140.0, 145.0]
}
```

Please note that the specific values provided above are just examples and may not reflect the actual distribution of FastingBS values for each target class. Further analysis and data exploration would be required to accurately determine the typical values.
