Four samples (k = 4) are taken from a process,

Four samples (k = 4) are taken from a process, with each sample consisting of five observations (n = 5). The sampled items are subjected to a stress test, and the amount of pressure, measured in pounds per square inch, required to crack each item was computed. The results are shown below. Develop an X chart to determine whether the process is stable or not. Click the icon to view the samples data, Click the icon to view the values of the Az constants. The upper controllimit is (Enter your response rounded to two decimal places.) The lower controllimitis (Enter your response rounded to two decimal places.) ) Plot the mean values, center line, and the control limits on the process control x chart.
