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 Heavy duty Medium duty Light duty Delicate duty Number of Double Rubs in thousands 15 9 15 3 9 3 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 Which statements are true about this situation The sales department can refer to fabric A as a medium duty fabric Fabric A is a more durable fabric because it has a lower double rub rating than fabric B The sales department can refer to fabric B as a medium duty fabric Neither fabric meets the requirements of a medium duty fabric Fabric B is a more durable fabric because it has a higher double rub rating than fabric A
