find UCL(x), LCL(x), based on the x chart is one or samples beyond the control limits?

find UCL(R), LCL(R), based on the r chart is one of more samples beyond the control limits? find UCL(x), LCL(x), based on the x chart is one

Twelve samples, each containing five parts, were taken from a process that produces steel rods at Emmanual Kodzi's factory. The length of each rod in the samples was determined. The results were tabulated and sample means and ranges were computed. The results were: Sample Sample Range (in.) 2 3 4 5 6 Sample Mean Range (in.) (in.) 9.204 0044 9.202 0.051 9 193 0042 9 208 0037 9.195 0.048 9.190 0053 7 8 9 10 11 12 Sample Mean (in.) 9.201 9 205 9.195 9.203 9.201 9.208 0.021 0.058 0 039 0038 0.054 0 061 0 Definition For the given data, the x 9 2012 inches (round your response to four decimal places) Based on the sampling done, the control limits for 3-sigma x chart are Upper Control Limit(UCL.;) - inches (round your response to four decimal places Lower Range D 0 0 Sample Size, n 2 3 4 6 6 7 8 9 10 12 Mean Factor, A2 1 880 1.023 0.729 0.577 0.483 0419 0.373 0337 0.308 0266 Upper Range, D 3268 2.574 2.282 2.115 2004 1.924 1.864 1816 1.777 1.716 0 0 0076 0.136 0 184 0223 0284 Enter your answer in the answer box and then click Check
