Once you$$ve opened the Excel spreadsheet, you will see a table listing all company employees and their hire dates, departments, salaries, bonuses, and performance review information for the past year.

Use what you learned about analyzing data in Excel on page $2\mathrm{.}4$ to carefully examine the employee performance data.

Using Excel functionality, you can find the answers to questions such as:

How much does the company spend on salaries, overtime, and bonuses overall?

Which departments have the highest employee expenses in total, and which departments have the highest average employee pay?

How long have employees been with the company on average, and how does that vary by department?

How does performance vary across employees and departments?

Do salaries seem to be tied to performance, experience, or length of employment? What about bonuses?

How much money does the company need to save in order to reduce its costs by $10$ percent?
