A Researcher Reports on a Study Conducted to Determine If

A researcher reports on a study conducted to determine if a new educational program has helped dialysis patients become more compliant with their fluid restrictions.

C) Findings of no difference are not surprising; it is difficult to make an impact on this population of patients.
D) There is a high likelihood that the sample size was not adequate, and the study should be replicated using more subjects.
