All else being equal, the decrease in the chance of making a Type I error comes at the cost of increasing the probability of making a Type II error.

D.

If the p-value is greater than the significance level, then the statistics falls into the reject intervals.

嗨,爱思考的PZer你好:


B的意思是,假设检验是针对从某个总体里面抽出的样本,进行计算,从而对另外一个总体进行推断。


假设检验的核心是通过样本数据对同一总体的参数进行推断,而非“从一个总体抽取样本去推断另一个总体的参数”
