Tire following data (in. ohms) are the resistance of resistors made on an automated machine. The mean and range of each sample are given in the right two columns, and the mean of sample means and the mean of sample ranges are given below these.
a. Develop sample mean and sample range control charts for resistance of resistors using the first 10 samples. Is the process in control?
b. Use the control charts developed in part a to decide if the eleventh sample (also given below) indicates an out-of-control situation.
