d.d.
If we consider "usual" heights to be those that convert to z scores between

The absolute difference is 194-183=11 cm.
I think the SD is more like 6 cm. I will use that
That is 11/6 or 1.83 of a SD.
A z-score is (x-mean)/sd
The z-score is 11/6 or +1.83
This falls within the (-2, 2) range and the height would not be considered unusual.
