标题[问题] 无母数可以检定mean吗?
时间Thu Mar 8 22:26:57 2007
题目是
When using the Mann-Whitney U test, the null hypothesis of interest is
A)Ho:the populations have equal mean values.
B)Ho:the populations have equal mean variances
C)Ho:the population realtive frequency distributions are identical
D)Ho:the populations are normally distributed
E)none of the above answers are correct
请问答案是A还是E呢
A)mean需要改成median才正确吗?
我的想法是
无母数还是可以检定未知母体分配的量资料
所以还是存在mean
所以答案是A
这样正确吗
谢谢
