6.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem. prp. 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 lieves there is no problem because his batteries have had an average life of 45 hours, about 10% longer than competitors' models. To raise the lifetime evel of technology not available to West. Nevertheless, he is concerned enough to set up hourly assembly line checks. Previously, after ensuring that the 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 XI 3 4 45 40 1 46 39 46 50 43 54 2 45 43 40 65 32 57 3 44 53 38 45 72 45 5 45 50 41 1 48 52 56 36 2 53 38 43 34 46 37 4 5 4840 52 53 29 49 53 42 X 44.8 48.2 42.8 42.0 von WN- R 18 15 27 19 25 Hour Sample R Taken 2 14 | 15 8 16 40 17 40 18 14 19 24 20 262 1 91 22 3023 30 27 24 20 25 47.8 X 45.0 45.0 41.0 46.2 44.4 52.8 40.0 45.8 41.4 45.6 45.6 47.2 49 37 46 8 19 55 47 5036 46.8 43.6 44.0 44.0 43.0 44.8 48.0 39 43 45 11 66 53 51 40 48 50 AAAA 57 43 30 56 12 44 47 4 2 13 44 44 36 46 57 our answer in each of the answer boxes. . is exercise contains only parts a and b. For the given data, the x = hours (round your response to three decimal places). For the given data, mean range = hours (round your response to two decimal places). With z=3, the control limits for the mean chart are: UCL;= hours (round your response to three decimal places). LCL = hours (round your response to three decimal places). The control limits for the range chart are: UCLR = hours (round your response to two decimal places). LCLR = hours (round your response to two decimal places). With these limits established, West now takes 5 more hours of data, which are shown in the following table. Calculate the mean and range for each hour that your responses for the mean to one decimal place and enter your responses for the range as whole numbers.)
