Based on the sampling done, the control limits

Based on the sampling done, the control limits for3-sigma x chart are:

Upper Control Limit (UCLx) = ____ inches(round your response to four decimal places).

Lower Control Limit (LCLx) = ____ inches(round your response to four decimal places).

Based on the x-chart, is one or more samples beyond the control limits? YES OR NO

For the given data, the R = ___ inches (round your response to four decimal places).

The control limits for the 3-sigma R-chart are:

Upper Control Limit (UCLR)= ____ inches(round your response to four decimal places).

Lower Control Limit (LCLR) = ____ inches(round your response to four decimal places).

Based on the R-chart, is one or more samples beyond the control limits? YES OR NO

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: For the given data, the x= inches (round your response to four decimal places)
