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. Day Monday Tuesday Wednesday Thursday Friday b. 23 c. 20.6 d. 19 e. 21 Weight Package 1 Package 2 Package 3 Package 4 23 23 20 18 18 14. The mean of all sample means is: a. 20 22 21 19 19 20 23 19 20 20 22 24 21 21 19 20 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 d. UCL-22.21; LCL e. UCL 23.7; LCL = 17.5 B 14.6 18.98 16. Is this process in control? a. Monday sample is above the UCL; all others are within limits. The process is not in control. b. Tuesday sample is above the UCL; all others are within limits. The process is not in control. c. Wednesday sample is below the LCL; all others are within limits. The process is not in control. d. Thursday sample is below the LCL; all others are within limits. The process is not in control. e. All samples are within limits. The process is in control
