SecureIT, Inc., is a small computer security contractor that provides computer security analysis, design, and software implementation for commercial clients. Almost all of SecureIT's work requires access to classified material or confidential company documents. Consequently, all of the security personnel have clearances of either Secret or Top Secret. Some have even higher clearances for work that involves so-called black box security work.

While most of the personnel information for SecureIT resides in database systems, a basic employee worksheet is maintained for quick calculations and ad hoc report generation. Because SecureIT is a small company, it can take advantage of Excels excellent list management facilities to satisfy many of its personnel information management needs. You have been provided with a sample worksheet, 3. Employee_Data, to assist SecureIT with producing several worksheet summaries. Here is what is needed:

1. One worksheet that is sorted by last name and hire data.

2. One worksheet that uses a custom sort by department in this order: Marketing, Human Resources, Management, and Engineering.

3. One worksheet that uses a filter to display only those employees in the Engineering department with a clearance of Top Secret (TS). 4. One worksheet that uses a custom filter to display only those employees born between 1960 and 1969 (inclusive).

5. One worksheet that totals the salaries by department and the grand total of all department salaries. This worksheet should be sorted by department name first.
