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. Day Mean Range Day Mean Range- 1 92.11 80 11 100.70 89 2 90.67 77 12 96.67 77 3 89.44 73 13 97.33 75 4 93.33 81 14 95.89 80 5 89.44 71 15 98.89 68 6 110.20 90 16 101.22 88 7 104.10 120 17 107.33 81 8 108.20 93 18 108.00 95 9 107.70 98 19 106.89 77 10 112.70 145 20 109.89 80 From the $\bar { x }$ chart we conclude that________.
