Q.35

What is the median number of employees assigned per project for the projects at Company Z?

(1) 25 percent of the projects at Company Z have 4 or more employees assigned to each project.
(2) 35 percent of the projects at company Z have 2 or fewer emplyees assigned to each project.

Ans: C

完全沒頭緒....
為什麼(1) + (2) 就可以知道中位數呢？ @@@

[汪汪北鼻]

35%(2)----30%(3)----25%(4)

由上圖可得知，中位數是3

[briandragon]

35%(2)----30%(3)----25%(4)

請問 30%(3) 士從哪裡來的??

[65kevin]

我想可能是筆誤吧.... 應該是 40%(3)

[chris8888]

yeah

2人含以下 35%

中間就是3人 40% (50%)(75%) <== 處於50%的位置就是median

4人含以上25%
