Based on prior knowledge, fasting blood sugar (FastingBS) is often used as an indicator of diabetes. In this case, we are using a threshold of 120 mg/dl to determine whether the fasting blood sugar level is normal or high.

To analyze the relationship between the feature (FastingBS) and the task (heart disease shown in coronary angiography), we can assume that high fasting blood sugar levels are associated with heart disease. However, it is important to note that this assumption should be validated using statistical analysis or medical expertise.

Based on this assumption, we can create the dictionary as follows:

```json
{
	"no": [70.0, 80.0, 90.0, 100.0, 110.0],
	"yes": [130.0, 140.0, 150.0, 160.0, 170.0]
}
```

Please note that these values are only examples and should be updated if more accurate information or specific data is available.
