10. Which of the following statement is true?
(A) In hypothesis testing, if we fail in rejecting the null hypothesis when it is actually false, then we make a Type I error.
(B) When we have the same sample to test the mean of a population around a specific value, it is more likely to reject the null hypothesis when we use one-tailed test than when we use two-tailed test under the same significant level.
(C) The probability of t-value less than that of the critical t-value of a significance level is equal to p-value.
(D) Using confidence interval to see whether it includes the specific population parameter may make different inference from doing hypothesis testing.
