No one is sure exactly how many men died in action or as a result of wounds
in Gallipoli. The number is somewhere between 8160 and 8710.

number of ANZAC soldiers killed in the Gallipoli Campaign who were less than
21 years old.

from the ANZAC soldiers who were less than 21 years old when they were killed
in the Gallipoli Campaign?

In the random sample of 520 ANZAC soldiers killed in the Gallipoli
Campaign only 1 man was an officer, the remaining 519 men were enlisted.
What percentage of the sample killed in Gallipoli was an officer?
