Based on my prior knowledge, I will analyze the relationship between the feature ALT_BLOOD and the presence of chronic heart failure (CHF) in myocardial infarction complications data. 

To determine the appropriate range of values for ALT_BLOOD, I will consider the normal range for Serum AlAT content. The normal range for AlAT (also known as Alanine Aminotransferase) in the blood is typically between 7 and 40 units per liter (U/L). Values above the upper limit of normal (40 U/L) may indicate liver damage or inflammation.

Now, let's analyze the relationship between ALT_BLOOD and the presence of chronic heart failure (CHF). We will consider two target classes: 'no' (indicating no chronic heart failure) and 'yes' (indicating chronic heart failure).

For the target class 'no' (no chronic heart failure), we can expect the ALT_BLOOD values to mostly fall within the normal range (7-40 U/L). Here are 5 typical ALT_BLOOD values for this target class: [10.5, 22.3, 35.8, 17.2, 29.6].

For the target class 'yes' (chronic heart failure), we may expect ALT_BLOOD values to be higher than the normal range. Here are 5 typical ALT_BLOOD values for this target class: [53.1, 79.4, 46.8, 68.2, 58.9].

Based on this analysis, we can create the following dictionary:

```json
{
	"no": [10.5, 22.3, 35.8, 17.2, 29.6],
	"yes": [53.1, 79.4, 46.8, 68.2, 58.9]
}
```
