A Type 2 error occurs when we fail to reject the null hypothesis even though it is false. Option A describes a Type 1 error, where we incorrectly reject the null hypothesis when it is actually true. Option B describes a correct decision, as we should not reject the alternative hypothesis if it is false. Option D describes a Type 1 error as well, as we are reporting significance when there is none.
