1. A production process is designed to fill boxes with an average of 14 ounces of cereal. The population of filling weights is normally distributed with a standard deviation of 3 ounces.
a. Calculate the centerline, the upper control limit (UCL), and the lower control limit (LCL) for the x¯x¯ chart if samples of 12 boxes are taken. (Round the value for the centerline to the nearest whole number and the values for the UCL and LCL to 3 decimal places.)
b. Analysts obtain the following sample means after a recent inspection of the production process. Can they conclude that the process is under control?
| x¯1=14.7x¯1=14.7 | x¯2=14.7x¯2=14.7 | x¯3=13.3x¯3=13.3 | x¯4=13.5x¯4=13.5 | x¯5=13.5x¯5=13.5 | x¯6=13.1x¯6=13.1 |
- Yes because all sample means lie within the control limits and there is no systematic pattern.
- Yes because some sample means lie outside the control limits.
- No because some sample means lie outside the control limits.
- No because even though all sample means lie within the control limits there is a negative trend.
