This exercise contains only parts a and b. a) 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: UCLx= hours (round your response to three decimal places). LCLx= 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). \begin{tabular}{cccc} \hline SampleSize,n & MeanFactor, & UpperRange,D4 & LowerRange,D3 \\ \hline 2 & 1.880 & 3.268 & 0 \\ 3 & 1.023 & 2.574 & 0 \\ 4 & 0.729 & 2.282 & 0 \\ 5 & 0.577 & 2.115 & 0 \\ 6 & 0.483 & 2.004 & 0 \\ 7 & 0.419 & 1.924 & 0.076 \\ 8 & 0.373 & 1.864 & 0.136 \\ 9 & 0.337 & 1.816 & 0.184 \\ 10 & 0.308 & 1.777 & 0.223 \\ 12 & 0.266 & 1.716 & 0.284 \end{tabular} Refer to Table S6.1. Factors for Computiog Control Chart Limits (3. sigma) for this problem. West Battery Corp. has recently been receiving complaints from retaliers that it 9-wolt batteries are not lasting as long as other name brands. James West, head of the TOM program at West's Austin plant, believes there is no probiem because his batteries have had an average life of 60 hours, about 10%6 longor 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 hourty 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: This exercise contains only parts a and b. a) For the given data, the x= hours (round your response to three decimal places).
