那位好心帮助看一下? 多谢!!!
131: 有11个数问median (1) 有5个数小于50 (2) 有5个数大于50 条件一,不可,条件二,不可,一加二,
选E
jj 主人说是E. I am not sure the answer. I think the median should be 50 if the number is an integer. Because (1)+(2) tells us that there are five numbers less than 50, and five numbers greater than 50, then the median should be 50. Can anyone tell me why the answer is E? Tons thanks. |
