Make a conclusion about the claim. A. In either case, one would be reluctant to conclude that the new mean is above 61 minutes. The sample size is large and the presence of two large outliers is evidence that the assumptions for inference are satisfied. B. In either case, one would be reluctant to conclude that the new mean is above 61 minutes. The sample size is small and the presence of two large outliers advises one to be cautious about conclusions from this sample. C. Because there are no outliers, the conditions for inference are met, and the confidence interval is entirely above 61 minutes, conclude that the new mean is above 61 minutes. D. Because there are no outliers, the conditions for inference are met, and the confidence interval includes 61 minutes, conclude that the new mean is above 61 minutes
