以下是引用siebel在2003-5-7 6:00:00的发言: 3、有10个数,其中7个数相同,问这10个数的average>median? (1)另3个数中每一个都大于这7个数; (2)另3个数的average > 这7个数的average;
median=7个数 1 ok. 2 ok. D
I have some problem with this question.
If these 10 numbers are ( 5 5 5 5 6 7 8 5 5 5), average 5.6 < median 6.,5.
When these 10 numbers are ( 5 5 5 5 5 5 5 6 7 8), average 5.6 > median 5 .
so we can say (1) is wrong.
(2) is wrong also.
Therefore, I would say correct answer is E. |
