Final answer:
To find the highest sales number for 2010 in cell B2, use the MAX function in a spreadsheet by selecting cell B2, entering '=MAX(range)' where 'range' is the range of cells containing 2010 sales numbers, and pressing Enter.
Step-by-step explanation:
The question involves finding the highest sales number for the year 2010 in a worksheet. To do this, one would typically use a function or feature in spreadsheet software that identifies the maximum value within a specific range of cells. If the data is in a column or row for the year 2010, you could use a MAX function to find the highest sales number. Here's how you could do it:
- Click on cell B2, where you want to display the highest sales number for 2010.
- Type in '=MAX(' and then select the range of cells that contain the sales numbers for 2010.
- Close the parenthesis and press Enter. The cell B2 should now show the highest value from the selected range.
If, however, the task also requires comparing observed and expected number of receipts, this might involve statistical analysis where observed values are compared to those expected under a specific hypothesis. This is not directly related to the question but is something to consider if the task involves more complex data analysis.
