[問題]GWD 12-Q25

Q25:

If each of the 8 employees working on a certain project received an award, was the amount of each award the same?

(1) The standard deviation of the amounts of the 8 awards was 0.
(2) The total amount of the 8 awards was $10,000.

ANS: A

題目是在問是否可被8整除.
那為什麼條件二不行呢? 10000/8=1250, 每人分$1250
答案應該是D?

因為題目只有告訴你這八個人都有領到一份獎賞. 問大家是不是得到一樣的數目

所以條件二只告訴你總額但是沒有告訴你,這八個人平分獎金,
你不可以自行除以八.
