B) "Statistical analysis might lead a researcher to reject a hypothesis."
C) "Statistical analysis provides proof of the relationships between variables."
D) "Statistical analysis supports inferences that a hypothesis is most likely correct (or most likely not correct)."
A, B, D
Feedback:
Hypotheses are formally tested through statistical analysis. Researchers use statistics to test whether their hypotheses have a high probability of being correct (i.e., has a probability < .05). Statistical analysis does not provide proof, it only supports inferences that a hypothesis is probably correct (or not). Hypotheses are never proved (or disproved); rather, they are accepted or supported (or rejected). "Statistical analysis provides proof of the relationships between variables" indicates that the nurse educator does not understand the purpose of using statistical analysis of quantitative research.
