O A. Yes, because even though there are no outliers, the sample data are highly skewed to the right.
OB. No, because the sample data are highly skewed but there are no outliers.
OC. Yes, because the sample data are highly skewed and there are outliers.
O D. No, because the sample data is roughly symmetric about the sample mean and there are no outliers.
(d) Construct and interpret a 95% confidence interval for the population mean wait time at the popular attraction.
Select the correct choice below and fill in the answer boxes to complete your choice.
