Recent evidence suggests that graduating from college during bad economic times can impact the graduate's earning power for a long time (Financial Times,June 1, 2012).

He expects the variance of the salaries to be different between these two years. The data are shown in the accompanying table and are contained in the accompanying Excel file.(You may find it useful to reference the appropriate table:z tableort table)
