NO.PZ2017092702000119 问题如下 Whiof the following statements about hypothesis testing is correct? A.The null hypothesis is the contion a researcher hopes to support. B.The alternative hypothesis is the proposition consiretrue without conclusive evinto the contrary. C.The alternative hypothesis exhausts all potentiparameter values not accountefor the null hypothesis. C is correct. Together, the null analternative hypotheses account for all possible values of the parameter. Any possible values of the parameter not coverethe null must coverethe alternative hypothesis (e.g., H0: θ ≤ 5 versus Hθ 5).原假设和备择假设一起了参数的所有可能值。 原假设未涵盖的参数值必须由备择假设涵盖（例如，H0θ≤5 与 Haθ 5）。 建立原假设和备择假设我们想证明可能错了或者说此时已经不相信的就放原假设H0，我们（因为已经有证据的支持）想要证明的就放H BC请翻译并且通俗点（着实没有get到题目想考察啥）

NO.PZ2017092702000119 老师视频明明说的是“不相信啥就H零。。。。想要拒绝他就H0。。。。” 原话！现在这个H0又变成真的了。。。。。晕死。。。。 c固然正确，。。。b很牵强！！！
