Many people who believe they may be suffering from the flu visit emergency rooms, where they are subjected to long waits and may expose others or themselves be exposed to various diseases. The article “Drive-Through Medicine: A Novel Proposal for the Rapid Evaluation of Patients During an Influenza Pandemic” (Annals Emerg. Med. 2010: 268–273) described an experiment to see whether patients could be evaluated while remaining in their vehicles. The following total processing times (min) for 38 individuals were read from a graph that appeared in the cited article:

a. Calculate several different measures of center and compare them.
b. Are there any outliers in this sample? Any extreme outliers?
c. Construct a boxplot and comment on any interesting features.
