119一个公司员工工资中数是35000，一共127人，问下面哪个对

1）at least 63 人大于或等于35000

2）at least 63 人小于35000

3）at most 63 人大于或等于35000

选只有1对

I think 1 is not right because 1 is same as saying that at most 64 people have income less than 35000. Well, if in the extreme case 64 people have income less than 35000, then 35000 is no longer the median. So I think none is right

1 is right if it says: at least 64 >= 35000 or at most 63 people less than 35000
