这是一条看图表的题目,求Yesterday each of the 35 members of a certain task force spent some time working on project P. The graph shows the number of hours and the number of members who spent that number of hours working on project P yesterday. What was the median number of hours that the members of the task force spent working on project P yesterday?

实在看不明白这张图表示什么含义。请大虾不吝赐教。 (图表贴补上来)

我这没题

从前有讨论过啊肯定。

记得是1小时多少人,2小时的多少人……

把所有人花的时间排列下来

1,1,1,1,1,1,2,2,2,2,2,……这样的,然后看中见那个就是第18个是几就是几了

9还是6还是多少记不得了
