You are working for a shoe manufacturer, and want to compare two different synthetic materials, a standard material A and a cheaper material B. You can afford to compensate12 young boys for experiments, so you planned to make six pairs with material A and another six pairs with material B, and ask six boys to wear A shoes and the remaining six to wear B shoes. Your quality control (QC) manager, however, suggests that each boy should wear a pair of shoes, the sole of one shoe made with material A and the sole of the other with B. And the decision as to whether the left or right sole was made with A or B is to be determined by the flip of a coin. Comment onthe suggestion of your QC manager.
