Assuming a process is in statistical process control based on both Xbar and R charts with sample size of $5$ per sub$-$group. The centerline of the XBar chart is $40$ and the average range R is $8.$ From Appendix A$,$ d$2=2\mathrm{.}326$ what is the process standard deviation? Using Q$3$ above, if the Upper Specification is $44$ and the Lower Specification is$36,$ what are the Z values and the Cp$?$ Can the process meet the required engineering tolerance of $8(44-36)?$ Comment in $1-2$ sentences.
