Directional hypotheses are also feasible in the case of tests of statistically significant differences.  The only difference is:
A) ignore the sign of the z value because we are only looking for a significant difference; the size of the z value.
B) that the z value for 95% is 1.64 and for 99% is 2.33.
C) we need to not only look at the z value but the sign to ensure the direction.
D) that the alternative hypothesis is called the directional hypothesis.
E) the null hypothesis states the opposite direction of difference to what the directional hypothesis is proposing.
