Based on prior knowledge, we can analyze the relationship between the feature "FastingBS" and the task of whether the coronary angiography shows a heart disease.

To determine the appropriate ranges of values for "FastingBS," we can refer to medical guidelines. Generally, a fasting blood sugar level greater than 120 mg/dl is considered high and may indicate diabetes or a potential risk for heart disease. On the other hand, a fasting blood sugar level of 120 mg/dl or below is considered normal.

Now, let's create a dictionary with the requested format, including 5 typical values for each target class ('no' and 'yes'):

```json
{
    "no": [95.0, 100.0, 105.0, 110.0, 115.0],
    "yes": [125.0, 130.0, 135.0, 140.0, 145.0]
}
```

In this example, for the target class 'no' (coronary angiography does not show heart disease), we have chosen hypothetical fasting blood sugar values within the normal range. Similarly, for the target class 'yes' (coronary angiography shows heart disease), we have selected hypothetical fasting blood sugar values above 120 mg/dl.

Please remember that these values are just examples and may not represent the actual relationship between FastingBS and the task.
