Based on my prior knowledge, I can provide a general analysis of the relationship between the feature "FastingBS" and the task of determining whether the coronary angiography shows heart disease. 

Typically, a fasting blood sugar level of below 100 mg/dl is considered normal, while a level of 100 to 125 mg/dl indicates prediabetes, and a level of 126 mg/dl or higher indicates diabetes.

For this task, we can assume that a FastingBS value of greater than 120 mg/dl can be considered as a positive indication of heart disease, while a value of 120 mg/dl or lower can be considered as a negative indication.

Based on this analysis, we can create a dictionary with the following format:

```json
{
	"no": [70.5, 85.0, 90.3, 100.8, 115.7],
	"yes": [125.9, 142.1, 155.4, 165.2, 175.6]
}
```

Please note that the values provided in the dictionary are just examples and may not be accurate representations of the actual distribution. You may update the values in the dictionary with more relevant or accurate values based on your domain knowledge or dataset.
