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 P02_30.xlsx.
b. Find the annual salary below which 75% of all given CEO salaries fall. $1,235,700
c. Find the annual bonus above which 55% of all given CEO bonuses fall. $
d. Determine the range of the middle 50% of all given total direct compensation figures, where the total is the sum of salary and bonus. IQR: $2,313,500
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. Round your answers to the nearest whole dollar, if necessary.
The standard deviation of the total for those whose total is below the 25th percentile of total is $324,300, whereas the standard deviation of the total for those whose total is above the 75th percentile of total is $XXX. There is much variability on the top end than on the bottom end.
