Problem 60E
Cereal box filling process. Refer to the data on weights of cereal boxes, Exercise 13.16 (p. 13-31). Assume the specification limits for the weights are USL = 24.2 ounces and LSL = 23.8 ounces. a. Assuming the process is under control, construct a capability analysis diagram for the process. b. Is the process capable? Support your answer with a numerical measure of capability.
ANSWER:
Step 1 of 4
We are given the data of weights on cereal boxes. And the specification limits are USL
and LSL are 24.2 and 23.8 ounces respectively.
a) We need to construct capability analysis diagram for the process by assuming the
process is under control.
Use MINITAB to construct the capability analysis diagram, using the following
instruction set:
1) Click on the Stat, “Quality tools”, Capability Analysis, and Normal.
2) Specify the quality variable “Day” in the Single column, and 5 in Sub group
size.
3) Specify the LSL value 23.8 in Lower spec, and USL value 24.2 in Upper
spec
4) Click Options button and tick Overall analysis under performance
analysis, and select percent under display.
5) Click Ok
