You are conducting a study on the blood glucose levels of 9 patients who are on strict diets and exercise routines.To monitor the mean and range of the blood glucose levels of your patients,you take a blood glucose reading every day for each patient for 20 days.The results are shown below.The mean of the 9 sample means is 101.03,and the mean of the 9 ranges is 86.9.The results are shown below. From the chart we conclude that________.
A) the glucose level is not in control for the nine patients on the diet and exercise program.
B) the glucose level means over the 20-day period fall within the control limits for the nine patients on the diet and exercise program.
C) exactly one mean is out of the control limits
D) some of the patients are not on a strict diet and exercise routine.
E) exactly two patients are out of the control limits

The control chart shows that all the mean values fall within the control limits, as indicated by the blue horizontal lines. The mean of the 9 sample means is also close to the target value of 100, which suggests that the diet and exercise program is effective in controlling the blood glucose levels of the patients. However, the range chart shows some variability in the individual glucose readings, with some patients having wider ranges than others. This could indicate that some patients are more responsive to the diet and exercise program than others, or that there are other factors that are affecting their blood glucose levels. Overall, the control chart indicates that the program is working well, but there is room for improvement in reducing the variability of the individual readings.
