Consider the top salary offer (in thousands of dollars) received by each member of a sample of 50 MBA students who graduated from the Graduate School of Management at Rutgers, the state university of New Jersey. Descriptive statistics and a box plot for the data are shown on the XLSTAT printouts below.

b. Based on the box plot for this data set, which salary offers (if any) are suspect or highly suspect outliers?
