PROBLEM A: Use the following to answer questions 14 - 16: A quality analyst wants to construct a sample mean chart for controlling a packaging process. Each day last week, he randomly selected four packages and weighed each. The data from that activity appears below. Weight Day Package 1 Package 2 Package 3 Package 4 Monday Tuesday Wednesday Thursday Friday 23 20 14. The mean of all sample means is: A) 20 B) 23 C) 19 D) 21 E) 20.6 15. Calculate 30 upper and lower control limits for the Mean. (a) UCL = 23.05; LCL - 18.15 (b) UCL-22.64; LCL - 18.56 (c) UCL-26.6; LCL - 14.6 (d) UCL-22.21; LCL - 18.98 (e) UCL-23.7; LCL - 17.5 16. Is this process in control? (a) Monday sample is above the UCL; all others are within limits. The process is out of control (b) Tuesday sample is above the UCL; all others are within limits. The process is out of control. (c) Wednesday sample is below the LCL; all others are within limits. The process is out of control (d) Thursday sample is below the LCL; all others are within limits. The process is out of control. (e) All samples are within limits. The process is in control
