Insert this statement

= Table.ReplaceValue(#"Tipo Alterado",each [Age],each if [Age] = null then List.Average(#"Changed Type"[Age]) else [Age],Replacer.ReplaceValue,{"Age"})

That's a good solution! I would actually calculate the List.Average first, make us a variable, so it'll calculate only once. So

avg = List.Average(#"Changed Type"[Column])

 

The in the formula, just replace the text above with avg
