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 employees assigned to each project.

请问,答案为什么是C呢?我一点思路也没有

根据(1)(2),40% 有3人,所以E

MEDIAN看的是从前算第50%的PROJECTS是多少个员工.1知道前25%是4个或以上,2知道后35%是2个或以下,那么从前26%到前65%都是3个人.所以MEDIAN一定是3. 楼主可以找下介绍MEDIAN的~ 不要和MEAN混了
