Based on prior knowledge, blood glucose levels can vary depending on age and health conditions. In the context of age groups, higher blood glucose levels are generally associated with older adults, while lower levels are associated with younger adults. Here's an analysis of the relationship between the LBXGLU feature and the age group target:

1. Adult:
   - Blood glucose levels for younger adults are typically below 100 mg/dL, so values in the range of 70-90 mg/dL can be considered typical for the 'Adult' age group.
   - Other possible values could include 75, 80, 85, and 95 mg/dL.

2. Senior:
   - Blood glucose levels for seniors can vary more widely, but higher values are more common. Values in the range of 100-150 mg/dL can be considered typical for the 'Senior' age group.
   - Other possible values could include 105, 115, 130, and 145 mg/dL.

Here is the dictionary with the LBXGLU values for each age group:

```json
{
	"Adult": [70.0, 75.0, 80.0, 85.0, 95.0],
	"Senior": [100.0, 105.0, 115.0, 130.0, 145.0]
}
