Based on prior knowledge, we can assume that the average yearly balance feature is a good indicator of whether a client will subscribe to a term deposit or not. Generally, clients with higher average yearly balances are more likely to subscribe to a term deposit.

To analyze the relationship between the average yearly balance feature and the task of subscribing to a term deposit, we can compare the typical balance values for each target class ('no' and 'yes').

```json
{
	"no": [500.0, 1000.0, 1500.0, 2000.0, 2500.0],
	"yes": [5000.0, 10000.0, 15000.0, 20000.0, 25000.0]
}
```

In this dictionary, we present 5 typical balance values for each target class. The values for 'no' class are [500.0, 1000.0, 1500.0, 2000.0, 2500.0] and the values for 'yes' class are [5000.0, 10000.0, 15000.0, 20000.0, 25000.0]. These values are just examples and might vary depending on the specific dataset and analysis.
