A new elementary algebra software is being integrated in the teaching of a developmental algebra course with the hope that it will help to improve the overall average score for the course. The historical average score for this course is 72. If a statistical test is to be done to determine the effect of this software on the average score, the alternative hypothesis will be:

a) ?":? ≠ 72

b) ?":? <>

c) ?":? ≥ 72

d) ?":? > 72
