Using the photo, what is the lower control limit and upper control limit?

Cartons of powder are supposed to weigh exactly 32 ounces. As the inspector on this production line you want to develop a process control chart. To that end you take 10 samples of six boxes each and weigh them. The results are as follows (the first number is the sample mean and the second is the sample range): Sample 1: 34.2 0.6 Sample 2: Sample 3: Sample 4: Sample 5: Sample 6: Sample 7: Sample 8: Sample 9: Sample 10: 34.3 0.3 34.2 0.4 34.1 0.7 34.2 0.3 34.3 0.4 34.0 0.5 34.1 0.8 34.2 0.4 34.4 0.3
