(Total 10 points) Day False 1 2 3 4 5 6 7 8 9 10 7 8 6 5 3 1 10 5 9 8 Positives a. Using a 3-sigma confidence level, generate a control chart for this blood testing process. (5 Points) b. Assuming that the blood testing service measures the false positives for day 11, 12, and 13 and finds that the number of false positives are 12, 15, and 13, respectively, is the process in control?
