A manufacturer of mugs packages them in boxes of 100. It is shown that, on the average, mugs weigh 100 grams and have a standard deviation of 5 grams. The manufacturer would like to determine whether too many mugs are being put in box, which happens if the overall weight (excluding the weight of the box) exceeds 10.04 kilograms. If they prepared 10,000 boxes of mugs, approximately, how many would be marked as “overweight”?
