A hospital administrator wants to investigate the quality of the patient meals served by the food-service department. She conducted a 14-day survey by submitting a questionnaire to the 500 patients with each meal, asking whether the meal was satisfactory or unsatisfactory. The results of the 12 samples are shown here. (a) Compute the p-bar, the overall proportion that is unsatisfactory. Give the answer in this format (0.00123) showing at least 3 significant figures. (b) Compute the control limits, LCL and UCL, for a p-chart using z = 3. (c) Create the p-chart. (d) is this process in control? Why or why not?
