1 2 3 A response management department is studying the time between a call received and a response team is deployed to manage the emergency situation. The department has gathered the data for randomly selected data for the last 20 weeks, 4 times each week, and recorded the data in minutes precisely to the second decimal point. The data is given below. 3 1.01 1.15 1.08 1.03 1.05 1.14 1.07 1.08 1.06 1.10 1.01 1.10 a. b. 15 6 7 B 4 0.98 1.13 1.06 1.03 1.08 1.00 1.10 1.04 1.11 1.11 1.06 1.05 1.14 1.16 1.13 1.14 1.04 1.01 1.02 1.05 1.07 1.05 0.97 9 10 1.13 1.16 1.06 1.07 1.02 1.03 1.05 1.14 17 12 13 14 15 16 1.08 1.11 1.09 1.05 1.07 1.05 1.03 1.00 1.07 1.13 0.95 1.04 1.07 1.08 0.99 1.05 1.09 1.15 1.10 1.06 1.04 1.08 1.06 1.04 1.08 11 18 19 20 1.01 1.08 1.09 1.08 1.08 1.07 1.05 1.11 1.02 1.04 1.06 1.15 Compute the mean and standard deviation of all 20 samples for the sample data. Calculate the control limits and construct the x and R-charts, using the 20 samples. Is the process under control at that point? c. The response management is interested in achieving specifications for the process at 1.065 ± 0.14 minutes. If the process is under control, calculate the capability indexes, Cpu, Cpl, and Cpk using the x and R-charts. What do the indexes indicate? 1 2 3 A response management department is studying the time between a call received and a response team is deployed to manage the emergency situation.
