Refer to Table 56.1. Factors for Computing Control Chart Limits (3 sigma) for this problem. West Battery Corp. has recently been receiving complaints from retailers that its 9-volt batteries are not lasting as long as other name brands. James West head of the TQM program at West's Austin plant, believes there is no problem because his batteries have had an average life of 55 hours, about 10% longer than competitors' models. To raise the lifetime above this level would require a new level of technology not available to West. Nevertheless, he is concerned enough to set up hourly assembly line checks. Previously, after ensuring that the process was running properly, West took samples of 5 9-volt batteries for 25 test to establish the standards for control chart limits. Those 25 tests are shown in the following table: Sample Data Sample Data Hour Sample Taken 1 2 3 4 5 6 7 1 57 49 54 59 54 65 40 57 2 54 53 41 61 44 66 38 73 3 4 5 46 56 56 63 50 60 54 43 63 57 55 57 58 57 51 57 6060 535361 58 49 46 X R 53.8 11 55.0 14 51.0 22 578 6 528 14 61.6 9 49.0 23 56.6 27 Hour Sample Taken 1 14 57 1561 16 67 1 7 44 18 68 19 61 20 65 21 57 2 3 62 44 4756 54 47 45 54 56 48 58 56 55 46 53 52 4 56 64 39 63 62 54 46 64 5 x 51 54.0 64 58.4 61 53.6 54 520 54 57.6 54 566 54 532 4654.4 R 18 17 28 19 20 7 19 18 Answ Enter your answer in each of the answer boxes ontt View all solutions sample defective Mean to search ars for Con 1 Definition cently beer Austin pl se the life checks. mart limits ne brands.
