(c) Is a large sample size needed to use Student's t-distribution to obtain a confidence interval for the population mean wait time at the popular attraction? Explain.
A. No, because the sample data are highly skewed but there are no outliers.
OB. Yes, because even though there are no outliers, the sample data are highly skewed to the right.
C. Yes, because the sample data are highly skewed and there are outliers.
OD. No, because the sample data is roughly symmetric about the sample mean and there are no outliers.
