O A. Yes, because the sample data are highly skewed and there are outliers.
B. Yes, because even though there are no outliers, the sample data are highly skewed to the right.
O C. No, because the sample data is roughly symmetric about the sample mean and there are no outliers.
D. No, because the sample data are highly skewed but there are no outliers.
