Lower Control Limit (LCLR) = ________ inches (round your response to three decimal places).

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

A) IN CONTROL

B) OUT OF CONTROL

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: Hour X R X R 1 3.35" 0.65" 3.31" 1.61" Hour 7 8 9 2 3.10 1.13 2.99 1.09 3 3.32 1.43 X R Hour X R Hour 3.15" 0.58" 13 3.11" 0.90" 19 2.75 1.08 14 2.93 1.36 20 3.02 0.66 15 3.12 1.11 21 10 2.75 1.33 16 2.94 0.50 22 11 2.83 1.12 17 2.96 1.43 23 12 2.87 0.45 18 2.64 1.29 24 2.75 1.03 4 3.29 1.31 3.38 0.41 5 3.07 1.12 3.04 1.53 6 2.86 0.32 2.64 0.97 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) = 3.719 inches (round your response to three decimal places). Lower Control Limit (LCL) = 2.295 inches (round your response to three decimal places). Based on the x-chart, the wire cutting process has been IN CONTROL The control limits for the 3-sigma R-chart are (round all intermediate calculations to three decimal places before proceeding with further calculations): Upper Control Limit (UCLR) = inches (round your response to three decimal places)
