[問題] 陳向東數學
想請問一題在 最新GRE數學預測模擬試題(一)的題目
25. the company at which Mark is employed has 80 employees each of whom has a
different salary. Mark's salary of $43,700 is the second-highest salary in the
first quartile of the 80 salaries. If the company were to hire 8 new employees
at salaries that are less than the lowest of the 80 salaries, what would
Mark's salary be with respect to the quartiles of the 88 salaries at the
company, assuming no other changes in the salaries?
A The 4th-highest salary in the first quartile
B The highest salary in the 1st quartile
C The 2nd-lowest salary in the 2nd quartile
D The 3rd-lowest salary in the 2nd quartile
E The 5th-lowest salary in the 2nd quartile
答案是E
如果插入的薪水是最低的八筆
不是應該不會影響到前面的四分位數嗎?
可是這樣看來就發現根本沒答案可選
好奇怪阿
請大家幫我解惑
謝謝大家!!
