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.

方案一中，25percent只是>4，并不知道具体是什么 35percent也只是<2，又没有具体的数值，假设如果25percent中很多是6、7个employees情况就大不一样了，如何算得出Median?
