You work in a factory that manufacture injection molded parts. As part of the quality control 20 samples of 5 parts each are collected and their compressive strength (in psi) are measured (see Table below) Sample Number xl 83.0 88.6 85.7 80.8 83.4 75.3 74.5 79.2 80.5 75.7 80.0 80.6 82.7 79.2 85.5 78.8 82.1 84.5 79.0 84.5 81.2 78.3 75.8 74.4 78.4 79.9 78.0 84.4 86.2 75.2 78.7 78.8 84.3 82.5 82.6 87.3 80.8 81.5 76.2 75.7 71.0 75.2...
6.15. Parts manufactured by an injection molding process are subjected to a compressive strength test. Twenty samples of five parts each are collected, and the compressive strengths (in psi) are shown in Table 6E.11. (a) Establish 7 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 GE.12. Plot the...
6.16. Reconsider the data presented in Exercise 6.15. (a) Rework both parts (a) and (b) of Exercise 6.15 using the i and s charts. (b) Does the s chart detect the shift in process vari- ability more quickly than the R chart did origi- nally in part (b) of Exercise 6.15? 6.15.
