please explain the concept and provide the solution

oe Below you find a control chart tx-chart) that is used to control a hole diameter in your production. The process mean (CL), the Upper and Lower Control Limits (UCL & LCL) and the Tolerance Limits (UTL & LTL) are indicated in the chart. 50 UT 45,000 45 UCL 38,840 35 CL 34840 LCL 30,840 30 25 LTL? 25.000 20 1:2 3:4 5878 9 10 11 12 13 14 15 16 17 18 10 20 21 22 23 24 2 Observations 6.1 Calculate the C process capability index (2pl ?1s the process capable? Motivate/justify your answer! (2p)

Explanation / Answer

6.1

6.2

Yes, the proces is in control as all the values of the observations are within the UCL, LCL limits

And each of those are within the UTL and LTL

USL= UTL 45.000 LSL= LTL 25.000 X bar = CL 34.840 3S = UCL-CL 4.000 S 1.333
