a) Identify the appropriate quality control chart(s) for this production. (Hint: First identify the type of measurement for this product, based on which then you can choose the appropriate chart(s).) b) Construct the control chart(s) you have specified in part (a). (As included in the instructions, you only need to identify the three elements of each quality control chart, namely, the CL, UCL, and LCL. No plotting is needed for this question. Same for the later questions.) c) The manager wants to use the control chart(s) you have constructed in part (b) to check a new production line. Table 2 below summaries the inspection results of 3 new samples drawn from the new process. Based on your analysis, do you think the new process is in control overall?

Question

Question 1: Resistors for electronic circuits are manufactured on a high-speed automated machine. To set up the machine and to create quality control tools to be used throughout the run, 8 samples were taken with 4 resistors in each sample. The complete list of these samples and their measured values are presented in Table 1 below.
