A quality analyst wants to construct a sample mean chart for controlling a packaging process. He knows from past experience that the process standard deviation is two ounces. Each day last week, he randomly selected four packages and weighed each
The data from that activity appear below.
Weight
Day Package 1 Package 2 Package 3 Package 4
Monday 23 22 23 24
Tuesday 23 21 19 21
Wednesday 20 19 20 21
Thursday 18 19 20 19
Friday 18 20 22 20
(a) Calculate all sample means and the mean of all sample means.
(b) Calculate upper and lower 2-sigma x-bar chart control limits that allow for natural variations.
(c) Based on the x-bar chart, is this process in control?
(a) The five sample means are 23, 21, 20, 19, and 20. The mean of all sample means is 20.6
(b) UCL = 20.6 + 2(2/ ) = 22.6; LCL = 20.6 - 2(2/ ) = 18.6
(c) Sample 1 is above the UCL; all others are within limits. The process is out of control.
