A researcher compares customer wait times at two bank branches. Branch A (n=60): mean = 4.2 minutes, Branch B (n=55): mean = 5.8 minutes. She runs 1200 simulations assuming equal wait times and finds that 84 simulations show differences of 1.6 minutes or greater (in either direction). She concludes the branches have significantly different wait times. What is the primary concern with this analysis?
