Based on prior knowledge, the range of typical blood pressure for the general population is between 90/60 mm Hg and 120/80 mm Hg. However, for the purpose of this analysis, we will focus on the diastolic blood pressure (the second number in the measurement) as it is more directly related to the task.

Analysis:
- High blood pressure (hypertension) is often considered to be a diastolic blood pressure of 90 mm Hg or higher.
- Normal diastolic blood pressure is typically below 80 mm Hg.

Based on this analysis, we can generate the following dictionary:

```json
{
    "yes": [90.1, 95.6, 96.4, 98.0, 100.5],
    "no": [71.2, 74.5, 78.9, 81.6, 84.2]
}
```

Please note that these values are just examples and should not be considered as actual thresholds for diagnosing diabetes. The purpose of this analysis is to showcase the relationship between diastolic blood pressure and the likelihood of having diabetes.
