Analysis of the relationship between the feature "previous" and the task of determining whether the client subscribes to a term deposit:

The feature "previous" represents the number of contacts performed before this campaign and for this client. Based on prior knowledge and understanding of the task, it is expected that the number of previous contacts would have an impact on the likelihood of a client subscribing to a term deposit. Typically, if a client has been contacted more times in the past, they may be more likely to subscribe to a term deposit.

To create the dictionary with the specific details, here are five typical previous values for each target class:

```json
{
	"no": [0.0, 2.0, 4.0, 6.0, 8.0],
	"yes": [1.0, 3.0, 5.0, 7.0, 9.0]
}
```

These values are just representative examples and may not be the exact values observed in the dataset. They aim to showcase a range of possible previous values for each target class, 'no' indicating clients who did not subscribe to a term deposit and 'yes' indicating clients who did subscribe.
