Based on my prior knowledge and analysis, the feature "day" represents the last contact day of the month. To determine the appropriate ranges of values, I will consider that a month typically has 30 or 31 days.

Analyzing the relationship between the feature "day" and the task of whether the client subscribes to a term deposit or not, it is likely that the particular day of the month does not have a strong direct influence on the outcome. However, it is possible that certain days may have a slight impact due to factors such as the timing of salary deposits, bill payments, or other financial activities.

Based on this analysis, here is the dictionary with the requested format:

```json
{
	"no": [15.0, 20.0, 25.0, 28.0, 30.0],
	"yes": [5.0, 10.0, 12.0, 18.0, 22.0]
}
```

Note that the values provided are just examples and may vary depending on the specific dataset being analyzed.
