EIn 1915 the average age of Australian and New Zealand soldiers was 28 years.
(i)How many years younger than 28 was the average age of the sample of ANZAC soldiers killed in Gallipoli?
(ii)Calculate this age difference as a percentage of 28.
FNo 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.
(i)Assuming the number is 8710, use the sample information to estimate the number of ANZAC soldiers killed in the Gallipoli Campaign who were less than 21 years old.
(ii)How many maths classes with 25 students in each class could have been made from the ANZAC soldiers who were less than 21 years old when they were killed in the Gallipoli Campaign?
4.The first ANZAC Division contained 30 000 men. Of these men, 631 were officers and 29 369 were enlisted men.
AOf the 631 officers only about onesixth had previous war experience. How many of the officers had no previous war experience?
BCalculate the percentage of the first Division who were officers.
CIn 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?
DOne T.V. commentator said: “If you are going to fight in a war, make sure you are an officer. Officers are less likely to be killed.”
Use your answer to parts (B) and (C) to determine whether the T.V. commentator’s statement is correct. Give a reason for your opinion.
