Points: 2.67 of 4 Save Janice Sanders, CEO of Pine Crest Medical Clinic, is concerned over the number of times patients must wait more than 30 minutes beyond their scheduled appointments. She asked her assistant to take random samples of 70 patients to see how many in each sample had to wait more than 30 minutes. Each instance is considered a defect in the clinic process. The table below contains the data for 15 samples. Number of Defects Number of Defects Number of Defects Sample Sample Sample 1 2 6 5 11 7 2 1 7 8 12 3 3 2 8 3 13 4 4 6 9 7 14 3 5 8 10 8 15 4 a.

At least one of the sample proportions is above the upper control limit, so the process is not in control. OB. At least one of the sample proportions is below the lower control limit, so the process is not in control. OC. The p-chart shows a significant upward trend, so the process is not in control. OD. All of the sample proportions are within the control limits and there are no unusual patterns, so the process is in control. OE. The p-chart shows a significant change in the wait times, so the process is not in control. Help me solve this View an example Get more help. Clear all Check answer
