Answer to Question 1

B

Answer to Question 2

B
Feedback:
A credibility assessment requires a careful analysis of the study's methodologic and conceptual limitations and strengths. Statistical testing results do not always have direct meaning, but often must be interpreted. Empirical evidence supporting research hypotheses never constitutes proof of their veracity. Correlation between two variables does not prove causation.
