Lower Control Limit(LCLx) =

*Based on the x-chart, the wire cutting process has been

For the given information, the average range R = i=124 Ri24=

For the given sample size, Upper Range (D4) =

For the given sample size, Lower Range(D3) =

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

Upper Control Limit(UCLR) =

Lower Control Limit(LCLR) =

Based on the R-chart, the wire cutting process has been ?

Refer to Table S6.1 - Factors for Computing Control Chart Limits ( 3sigma) for this problem. Sampling 4 pieces of precision-cut wire (to be used in computer assembly) every hour for the past 24 hours has produced the following results: Based on the sampling done, the control limits for 3 -sigma x chart are (round all intermediate calculations to three decimal places before proceeding with further calculations): Upper Control Limit (UCL)= inches (round your response to three decimal places)
