Consider a process under statistical quality control. The upper specification limit of the statistic of interest is 119, while the lower specification is 32. The sample plan is for 9 samples per period. The average range of the process is 13. The process overall mean is 69. What is the capability of the process assuming it is not centered exactly between the specification limits and the statistic of interest has a normal distribution?

Consider a process under statistical quality control. The upper specification limit of the statistic of interest is 138, while the lower specification is 42. The sample plan is for 9 samples per period. The average range of the process is 17. The process overall mean is 61. What is the capability of the process assuming it is not centered exactly between the specification limits and the statistic of interest has a normal distribution?
