Researchers for a textile company carried out an experiment comparing the longevity of two new fabric blends. They carried out a series of usage tests, known as double rubs, on 100 pieces of each type of material. These scales are used for this type of testing.

Fabric Grade Number of Double Rubs
(in thousands)
Heavy duty
Medium duty
Light duty
Delicate duty
After performing the tests on each fabric, researchers found that on average, fabric A lasted through 7,900 double rubs and fabric B lasted through 9,200 double rubs.

The marketing department wants to advertise that both fabrics are tested and approved for medium-duty use.
