Instructions: Construct a quality control chart

Instructions: Construct a quality control chart means to specify the values of the three basic elements of the chart (CL, UCL and LCL). 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 be used throughout the run, 8 samples were taken with 4 resistors in each sample. The complete list of samples and their measured values are presented in Table 1 below. Sample 1 1010 986 2. 995 Readings (in OHMS) 991 985 996 1009 1003 1015 1020 1009 1019 1005 994 1008 3 990 4 1015 998 Table 1 5 1013 993 6 994 1001 994 1005 7 989 992 982 1020 8 1001 986 996 996 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). 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?
