he operations manager of a plant that manufactures tires wants to compare the actual inner diameters of two grades of​ tires, each of which is expected to be 575 millimeters. Samples of five tires from each grade were​ selected, and the results representing the inner diameters of the​ tires, ranked from smallest to​ largest, are shown below. Complete parts​ (a) through​ (b) below. Grade X                                      Grade Y 565, 570, 577, 581, 584              572, 574, 577, 580, 583
