Based on my prior knowledge, ALT_BLOOD is a measure of Serum AlAT content, which is an enzyme found mainly in the liver. Higher levels of ALT_BLOOD are generally indicative of liver damage. However, there is no direct relationship between ALT_BLOOD and chronic heart failure. Therefore, I cannot determine the appropriate ranges of values for ALT_BLOOD in relation to chronic heart failure.

To generate the requested dictionary, I will assume that the values for the target class 'no' represent patients without chronic heart failure and the values for the target class 'yes' represent patients with chronic heart failure. However, please note that this assumption is based on the given task and not on the actual relationship between ALT_BLOOD and chronic heart failure.

Here is the dictionary with 5 typical ALT_BLOOD values for each target class:

```json
{
	"no": [12.5, 14.3, 13.6, 17.2, 15.9],
	"yes": [19.8, 21.5, 18.6, 22.4, 20.1]
}
```
