[計量] PP2計量一問
If the average (arithmetic mean) of x,y,z,5 and 7 is 8,which of
the following must be true?
I.The median of the five numbers cannot be 5.
II.At least one of x,y and z is greater than 9.
III.The range of the five numbers is 2 or more.
答案給 II 和 III
我不太懂的選項是III
我現在想到的解釋是 range是指五個數字中最大跟最小的差距
是這個意思嗎???
