To analyze the relationship between the RestingBP feature and the presence of heart disease, I will use my prior knowledge to determine appropriate ranges of values for each target class ('no' and 'yes').

Based on medical understanding, normal blood pressure generally falls within the range of 90/60 mm Hg to 120/80 mm Hg. However, it is important to note that blood pressure can vary significantly between individuals. 

Considering this information, I will assume the following ranges for each target class:

- 'no' (no heart disease): RestingBP values below 120/80 mm Hg.
- 'yes' (heart disease): RestingBP values equal to or above 120/80 mm Hg.

Now, let's generate the dictionary with the specified format:

```json
{
	"no": [90.0, 100.0, 110.0, 115.0, 118.0],
	"yes": [120.0, 125.0, 130.0, 140.0, 150.0]
}
```
Note that these values are just examples and can vary depending on the available data and the specific model used for analysis.
