Assignment Chapter 13 1. Ten samples of 20 parts each were taken from an ongoing process to establish a p-chart for control. The samples and the number of defectives in each are shown in the following table: # DEFECTIVE ITEMS IN # DEFECTIVE ITEMS IN MPLESAMPLE SIZETHE SAMPLE SAMPLE SAMPLE SIZE SAMPLE 20 20 20 20 20 20 20 20 20 10 a. Develop a p-chart using z-3. (3 pts) b. Based on the plotted data points, is the process under control? (2 pts) 2. C-Spec, Inc., is attempting to determine whether an existing machine is capable of milling an engine part that has a key specification of 4 t.003 inches. After a trial run on this machine, C-Spec has determined that the machine has a sample mean of 4.001 inches with a standard deviation of 0.002 inch. a. Calculate the process capability index (Cpk) for this machine. (3 pts) b. Shoul d C-Spec use this machine to produce this part? Why? (2 pts) help
