卡方一致性檢定 與 兩樣本(p1-p2)比例檢定
我的疑問是
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成大國企)
我想請問的是 當抽樣數像這題一樣才20的時候 (當然也沒說符合常態)
也可以用兩樣本比例"Z檢定"嗎?
p1-p2~Z 不是在大樣本底下才會近似嗎?
(答案用兩樣本檢定)
那這題用卡方一致性檢定會不會更適合?
感謝
而且兩種作法出來的答案完全不一樣...
