Based on prior knowledge, blood glucose levels can vary based on age and health conditions. In general, fasting blood glucose levels are used to diagnose diabetes and prediabetes. 

For the age group "Adult", which typically refers to individuals below the age of 65, the normal range for fasting blood glucose is usually between 70 mg/dL and 100 mg/dL. Therefore, we can consider values within this range as typical for the "Adult" age group.

For the age group "Senior", which typically refers to individuals aged 65 and above, normal fasting blood glucose levels may be slightly higher. A commonly accepted range for seniors is between 80 mg/dL and 130 mg/dL.

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

```json
{
	"Adult": [70.0, 80.0, 90.0, 95.0, 100.0],
	"Senior": [80.0, 90.0, 100.0, 110.0, 120.0]
}
```

Please note that these are just example values within the respective ranges and may not be representative of a complete analysis.
