Based on prior knowledge, normal blood pressure ranges would be between 90/60 mmHg to 120/80 mmHg. Resting blood pressure values above this range could potentially indicate hypertension, which is a risk factor for heart disease. However, it's important to note that blood pressure alone may not provide a definitive diagnosis for heart disease.

Based on the task of determining whether the coronary angiography shows a heart disease, we can analyze the relationship between RestingBP and the target variable. We need to find typical RestingBP values for each target class to understand if there is any correlation.

To create the desired dictionary, we will look at typical RestingBP values for each target class ('no' and 'yes').

Here is the dictionary with 5 typical RestingBP values for each target class:

```json
{
	"no": [120.0, 115.0, 110.0, 125.0, 132.0],
	"yes": [138.0, 144.0, 152.0, 129.0, 136.0]
}
```

Please note that these typical values are hypothetical and you should analyze real data to get accurate results. This analysis is based on general knowledge and assumptions.
