Step 1 :The test statistic, t, is 4.96 and the P-value is 0.000. In hypothesis testing, a P-value less than 0.05 is typically considered statistically significant, meaning we would reject the null hypothesis. The null hypothesis in this case would be that there is no difference in creativity between the red and blue backgrounds. Since the P-value is less than 0.05, we reject the null hypothesis. Therefore, there is sufficient evidence to support the claim that blue enhances performance on a creative task.
Step 2 :Final Answer: \boxed{\text{A. Reject the null hypothesis. There is sufficient evidence to support the claim that blue enhances performance on a creative task.}}
