3 The Wall Street Journal CEO Compensation Study analyzed CEO pay from many U.S. companies with fiscal year 2008 revenue of at least $5 billion that filed their proxy statements between October 2008 and March 2009. The data are in the file CEO Compensation.xlsx. a) Create a histogram and a boxplot to gain a clearer understanding of the distribution of total income (salary + bonus) earned by the surveyed CEOs in fiscal 2008. How would you characterize this distribution? b) Find the annual total income below which 75% of all given CEO salaries fall. c) Find the annual total income above which 55% of all given CEO bonuses fall. Determine the range of the middle 50% of all given total income figures. For the 50% of the executives that do not fall into this middle 50% range, is there more variability in total direct compensation to the right than to the left? Explain
