Recall that if the p-value is less than alpha in a one-tailed test, this means that the observed statistic lies in the rejection region. The name "rejection" refers to the rejection of the null hypothesis.


So if the p-value is less than alpha in a one-tailed test, then the null hypothesis should be rejected.


So the answer is C)
