Final answer:
To find the highest sales number for 2011 in the Top Performers worksheet, normally you would use a spreadsheet function such as =MAX(range) in cell B3, but the question seems to contain information on global population that is not directly related to sales data.
Step-by-step explanation:
To determine the highest sales number for 2011 in cell B3 of the Top Performers worksheet, you would generally use a spreadsheet function or manually scan through the data for 2011 to find the maximum value. However, the information provided in the question seems to be misplaced, as it refers to the global population in billions and a table related to predictions, which does not directly relate to finding the highest sales number. Thus, it's crucial to ensure that you are looking at the correct dataset for sales numbers.
If you were to locate the highest sales number, you could use a formula such as =MAX(range), substituting 'range' with the actual range of cells that contain the sales data for 2011. Once the formula is entered into cell B3, it will return the highest sales value for that year. Additionally, you may want to verify the accuracy of the data if manual errors are a possibility before making any business decisions based on this figure.
