问题如下:
What does a hypothesis test at the 5% significance level mean?
选项:
A. P(not reject H0 | H0 is true) = 0.05
B. P(not reject H0 | H0 is false) = 0.05
C. P(reject H0 | H0 is true) = 0.05
D. P(reject H0 | H0 is false) = 0.05
解释:
The significance level is the probability of committing a type 1 error, or rejecting a correct model. This is also P(reject H0 | H0 is true). By contrast, the type 2 error rate is P(not reject H0 | H0 is false).
这道题是问type one error吗?
