note:LCLx was incorrect.

b) Based on the x chart the wire cutting process has been? out of control or in control

c) the control limits for the 3-sigma chart are (round all intermidate calculations to 3 decimal places)

UCLr=? inches

LCLr=? inches

d) based on the r chart, the wire cutting process has been? out of control or in control

Refer to Table 56.1 - Factors for Computing Control Chart Limits (3 sigma) 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: Hour 1 2 3 AWN- R 3.25" 0.76" 3.20 1.23 3.12 1.48 3.291.31 3.07 1.22 2.86 0.37 Hour 7 8 9 10 11 12 R 0.48" 1.18 0.76 1.33 1.12 0.45 2.95" 2.55 3.02 2.75 2.83 2.87 Hour 13 14 15 16 17 18 21 R Hour 0.90" 19 1.36 | 202 1.11 0.55 22 1.38 23 2 1.24 24 .01" 2.73 3.22 2.84 2.76 2.84 3.31" .89 2.55 3.38 .94 2.64 R 1.66" 1.09 1.03 0.41 1.58 1.02 Based on the sampling done, the control limits for 3-sigmax chart are (round all intermediate calculations to three decimal places before proceeding with further calculations): Upper Control Limit (UCL;-) = 3.713 inches (round your response to three decimal places). Lower Control Limit (LCL,) = 2.789 inches (round your response to three decimal places).
