Bronze award: quality control
Students imagine they work in the quality control department of a company that manufactures pre-packaged consumer products. Their job is to sample packages to check that they contain the right mass or volume of product. If not, the filling machines need adjusting. They will need to check the weight of the contents of at least 10 packs of food, and work out whether they comply with the e-mark rules - both for average mass and for ‘negative tolerance’.
The e-mark (℮) means that the average contents of a packet must be at least the nominal amount shown on the label - if not, the company may be fined for selling short measure. If the average is much more than the nominal amount, it means the company is giving away extra product, reducing its profits.
