问题如下图:
选项:
A.
B.
C.
D.
D选项为什么不对?1类错的几率上升,对应二类错的几率就下降

NO.PZ2019040801000075问题如下Whiof the following outcomes woulmost likely occur with a crease in the confinlevel?A.Increaseprobability of making a Type I error.B.creaseprobability of making a Type I error.C.Increaseprobability of making a Type II error.creaseprobability of making a Type II error.A is correct.考点Type one error Type two error解析减小confinlevel也就是增加significanlevel,比如99%的confinlevel 减小到95%,这会减少接受域的面积,增加拒绝域的面积,也就是更容易拒绝原假设,更容易犯第一类错误。两者是相反的吗?此消彼长的吗
NO.PZ2019040801000075 我看老师的讲义写的是error1上升,error2下降
creaseprobability of making a Type I error. Increaseprobability of making a Type II error. creaseprobability of making a Type II error. A is correct. 考点Type one error & Type two error 解析减小confinlevel也就是增加significanlevel,比如99%的confinlevel 减小到95%,这会减少接受域的面积,增加拒绝域的面积,也就是更容易拒绝原假设,更容易犯第一类错误。significanlevel和confinlevel 的区别麻烦再说一下
请问一下type I error的概率上升 type II error概率不就下降么 那应该对呀
