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. (Note: This data set is a somewhat different CEO compensation data set from the one used as an example in the next section.)

a. Create a pivot table and a corresponding pivot chart that simultaneously shows average of Salary 2008 and average of Bonus 2008, broken down by Company Type. Comment on any striking results in the chart.

b. In the Data sheet, create a new column. Total 2008, which is the sum of Salary 2008 and Bonus 2008. Then create two pivot tables and corresponding pivot charts on a single sheet. The first should show the counts of CEOs broken down by Company Type, and the second should simultaneously show the average of Total 2008, the minimum of Total 2008, and the maximum of Total 2008 all broken down by Company Type. Comment on any striking results in these charts.
