B. alpha should be changed.
C. the null hypothesis should be rejected.
D. the null hypothesis should not be rejected.

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)
