问题如下：
Here is some information about the Type I error and Type II error. Type I error= 8%. Type II error= 25%. What is the significance level and the power of test?
选项：
A.
8% and 75%.
B.
92% and 75%.
C.
92% and 25%.
解释：
A is correct.
P(Type I error)= α = significance level = 8% .
Power of test= 1 - P(Type II error) = 1 - 25% = 75%.
Significance level=Type1error和P-value=1-Type2error的原理怎么理解好呢？总记错

B.92% an75%. C.92% an25%. A is correct.P(Type I error)= α = significanlevel = 8% .Power of test= 1 - P(Type II error) = 1 - 25% = 75%. 老师，怎么理解a=significanlevel=P(error I) =1-confinlevel
