A researcher conducted an experimental study examining the impact of a new curriculum on ninth graders' achievement as measured by the state proficiency exam. The participants, who were enrolled in a large, urban school district, were placed in treatment and control groups by classroom.

the new curriculum. The researcher concluded that the results supported her research hypothesis. Which conclusion is MOST reasonable given this information?
a) The new curriculum would be effective for all ninth-grade students.
b) The new curriculum is a much better curriculum than the old curriculum.
c) The new curriculum is likely a more effective method than the traditional method with ninth graders from a large, urban district.
