标题卡方一致性检定 与 两样本(p1-p2)比例检定
时间Fri Mar 2 01:54:36 2007
我的疑问是
Tainan Ltd. Co. provided the following data as an example of selection
among 20 male and female applicants for 15 open positions:
selected no selected total
-----------------------------------------
Male 10 10 20
Female 5 15 20
Using the above data to show and discuss whether Tainan has a selection bias
in favor of males for the 15 open positions at a statistical significance
level of alpha = 0.1 (95成大国企)
我想请问的是 当抽样数像这题一样才20的时候 (当然也没说符合常态)
也可以用两样本比例"Z检定"吗?
p1-p2~Z 不是在大样本底下才会近似吗?
(答案用两样本检定)
那这题用卡方一致性检定会不会更适合?
感谢
而且两种作法出来的答案完全不一样...
