Dr. Sterling conducted a study comparing the empathy scores of two groups of violent offenders (a rehabilitation group and a control group) using a Mann–Whitney U test. His calculated (observed) value of U U\,U was 14. The critical value of U U\,U for a one-tailed (directional) hypothesis at p≤0.05 p \le 0.05\,p≤0.05 is 15.
Determine whether Dr. Sterling's results are statistically significant.
