Based on prior knowledge, the relationship between BMI and the likelihood of having diabetes can be analyzed as follows:

Analysis:
- People with higher BMI values are more likely to have diabetes compared to those with lower BMI values. Higher BMI is associated with increased risk of obesity, which is a major risk factor for developing type 2 diabetes.

Based on this analysis, the dictionary would look like this:

```json
{
	"yes": [35.0, 37.5, 40.3, 42.1, 46.2],
	"no": [19.8, 22.6, 24.9, 26.7, 28.4]
}
```

Please note that these BMI values are just examples and may not be accurate representations of the actual distribution of BMI values for people with and without diabetes. The values provided should be used for illustrative purposes only.
