Question 2) Small boxes of Corn-Flakes cereal are labeled "net weight 10 ounces." Each hour random sample of size n 4 boxes are weighed to check process control. Five hours of observations yielded the following data: = TIME 9 AM 10 AM 11 AM Noon 1 PM BOX 1 9.8 10.1 9.9 9.7 9.7 WEIGHTS BOX 2 10.4 10.2 10.5 9.8 10.1 BOX 3 9.9 9.9 10.3 10.3 9.9 a) Using these data, construct limits for x-bar and R charts. b) Is the process in control?
