If a hypothesis test leads to the rejection of the null hypothesis : (A) a type I error is always committed. : (B) a type I errormay have been committed only. : 請問答案各是多少呢 : 謝謝 不好意思我錯了orz~答案是B沒錯 1. (D)的翻譯是 虛無假設只會在證據顯著不支持H0時被保留 ==>明顯錯了 (C) 虛無假設只會在證據支持H0時被保留,這句話也是錯的,就算證據不 支持他,我們還是假設虛無假設成立. (A) 很明顯就錯了 真是不好意思(跪) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.115.177.186
