To determine the relationship between the feature RestingBP (resting blood pressure) and the task of whether the coronary angiography shows heart disease, I will analyze the typical ranges of blood pressure values associated with each target class.

Before proceeding, it's important to note that the appropriate ranges of values for blood pressure can vary based on factors such as age, sex, and overall health of the patient. However, based on general knowledge, the American Heart Association's guidelines for adults can be used as a reference:

- Normal blood pressure (no heart disease): Systolic BP < 120 mm Hg and Diastolic BP < 80 mm Hg
- High blood pressure (heart disease): Systolic BP >= 130 mm Hg or Diastolic BP >= 80 mm Hg

Based on these guidelines, we can create the desired dictionary:

```json
{
	"no": [115.0, 118.0, 112.0, 122.0, 116.0],
	"yes": [130.0, 138.0, 135.0, 125.0, 142.0]
}
```

In this example, I have included 5 typical RestingBP values for each target class ('no' and 'yes') in line with the blood pressure ranges specified by the American Heart Association. These values are presented as floats in the lists. Please note that these values are just an example and may not accurately represent the specific relationship between RestingBP and heart disease in the given context.
