To determine the correct comparisons between the sales for each month listed in your query, I would need to know the specific sales figures for each of these months (April, May, February, March, and June). Without the actual sales values or the variances from the average sales of $12 million, I cannot accurately complete the comparisons.
If you provide the sales figures for each month, I can help you correctly identify whether each month's sales were greater than, less than, or equal to the average of $12 million, and complete the comparisons accordingly.
