Delpack manufactures 15 different wire harnesses for the Big 3 automakers (coded as B1, B2, and B3). The wire harnesses are also coded by their current draw in amps (A1, A2, A3, A4 and A5). Given the following defect data (defects per batch of 100), indicate if there is a problem and where is located. (A1B1=5, A2B2=0, A3B3=0, A1B2=3, A2B3=1, A1B3=4, A2B1=1, A3B2=1, A4B3=0, A3B1=0, A4B2=0, A5B3=0, A4B1=0, A5B1=0, A5B2=0)
