Based on prior knowledge, in the context of fasting blood sugar levels and heart disease, a fasting blood sugar level of greater than 120 mg/dl is generally considered high and may indicate the presence of heart disease. A fasting blood sugar level of 120 mg/dl or lower is typically considered normal and may suggest the absence of heart disease.

Therefore, we can perform the analysis as follows:

For the target class "no" (absence of heart disease), typical FastingBS values could be:
- 110.5
- 105.6
- 95.0
- 100.2
- 119.3

For the target class "yes" (presence of heart disease), typical FastingBS values could be:
- 140.7
- 133.9
- 128.1
- 150.2
- 165.8

Based on this analysis, the dictionary would be:

```json
{
	"no": [110.5, 105.6, 95.0, 100.2, 119.3],
	"yes": [140.7, 133.9, 128.1, 150.2, 165.8]
}
```
