Answer 1: a. From the given table, it has been found that there are seven observation samples about the waiting time of patients at the chamber of Dr. Patel. On the basis of 12 days, the waiting period of those patients has been expressed in the following table. Through the sample of data, a control chart has been drawn to show its average value based on the upper and lower limit. The larger value is considered to be UCL and smaller values refer to LCL. An x bar chart has been drawn with the help of excel to examine the performance of the average value. Also, an R chart has been shone through the figure to monitor the range of the sample values of each day. In the following study, some formal has been shown in which values have been put to calculate the desired data.
