Problem Solving Questions (Supplement 6: Statistical Process Control] The Pet-Pal Company produces delicious dog treats. Management wants the filling process to be properly adjusted so that the process average weight per packet is 68 grams. To make sure that the process is in control, an inspector at the end of the filling process periodically selects a random sample of 10 packets and weighs each packet. The mean and range for each sample are then recorded. The results from the last 5 samples are shown in the table below. Sample Mean Range 1 67 2 3 4 5 66 73 65 69 6 10 7 8 Answer the following questions. Write your final answer only (without intermediate steps) in the blanks below. Use 2- decimal accuracy for the final answer, e.g.,0.12, when necessary. Question 33 (4 points) The mean of the sample means i.e., X) - Use 2-decimal accuracy for the final answer, e... 0.12, when necessary, Question 34 (4 points) A Use 2- The average range (i.e., R) - decimal accuracy for the final answer, e.g., 0.12, when necessary. Compute control limits for the X-chart and R-chart. Factors for computing control chart limits are provided in Table M1 below.

Question 36 (4 points) For the R-chart: Upper Control Limit (UCL) = A . Lower Control Limit (LCL) - Use 2-decimal accuracy for the final answer, e.g., 0.12, when necessary. Question 37 (4 points) Is the process in statistical control? No. Cannot tell; more information is needed. Yes
