Answer all six parts complete and correct otherwise don't even think of attempting!!!

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 overbarx chart are (round all intermediate calculations to three decimal places before proceeding with furthercalculations): Upper Control Limit (UCL Subscript x overbarUCLx) = ? Lower Control Limit (LCL Subscript x overbarLCLx) = ? Based on the x overbarx-chart, the wire cutting process has been IN CONTROL or OUT OF 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 (UCL Subscript Upper RUCLR) = ? Lower Control Limit (LCL Subscript Upper RLCLR) = ? Based on the R-chart, the wire cutting process has been IN CONTROL or OUT OF CONTROL ?
