Question 4: Use Data4 Sheet

This table reports Revenue and Customer of 3 divisions (A, B, C) of a corporation over time

4a. Create a table reporting the average annual revenue for each division.

( Note: So each division, you have only 1 number for average)

Report the SUM of the 3 average numbers for these 3 divisions (do NOT include or use the Grand Total) in that table?

4b. Create a table reporting total revenue for each year for the whole corporation.

So your table should have 16 rows (or columns) associated with 16 years

(Note: Total sales of the corporation equals to the sum of 3 divisions sales)

Sort your table on year (Smallest to Largest)

From that table, report the SUM of total sales of the 3 years: 2000, 2001 and 2002.

4c. Create a reporting the total sales for each division in each period (you have a column called period in the original table). See the table below.

Sort Division from A to Z and sort period from Largest to Smallest.

Report the SUM of the Top left and Bottom Right number (highlighted in the table below).

(do not include Grand total in your calculation)
