6.21. Parts manufactured by an injection molding process are subjected to a compressive strength test. Twenty samples of five parts each are col- lected, and the compressive strengths (in psi) are shown in Table 6E.12. (a) Establish x and R control charts for compressive strength using these data. Is the process in statis- tical control? (b) After establishing the control charts in part (a), 15 new subgroups were collected and the com- pressive strengths are shown in Table 6E.13. Plot the i and R values against the control units from part (a) and draw conclusions. 6.22. Reconsider the data presented in Exercise 6.21. (a) Rework both parts (a) and (b) of Exercise 6.21 using the x and s charts.
