If the probability that fail to reject the null hypothesis when it actually false increases, how about the confidence level? A Increase. B Decrease. C No change. 查看解析 上一题 提交试卷 正确答案A 您的答案B本题平均正确率：52% Type I error and Type II error难度：一般 推荐：      答案解析 When the probability of Type II error increase, the probability of Type I error will decrease, which means that the significance level (α) will decrease. The confidence level = 1- significance level. Therefore, the confidence level will increase. 请问： confidence level 是中间区域的面积是概率的概念对吗？ confidence level 的宽度才是2倍的1.96（这里是举例）？
