Test the Null Hypothesis: “There will be no significant difference in the BB2 mean scores of Group A and Group B”

The t-test comparing the mean BB2 scores between Group A and Group B resulted in a T-statistic of 3.53 and a P-value of 0.0078. Since the P-value is less than 0.05, we reject the null hypothesis, indicating there is a significant difference in the BB2 mean scores between Group A and Group B.
