For a test of a mean, which of the following is incorrect?

A) If H0: μ ≤ 100 and H1: μ > 100, then the test is right-tailed.

B) H0 is rejected when the calculated p-value is less than the critical value of the test statistic.

C) The critical value is based on the researcher's chosen level of significance.

D) In a right-tailed test, we reject H0 when the test statistic exceeds the critical value.
