A manufacturer uses two machines to package its product. A quality engineer wants to assess the process capability of each machine. The engineer randomly samples 50 packages from each machine and records the weight of each package. The specification range is 31 oz ± 4 oz. The engineer knows that the distribution of weights follows the largest extreme value distribution.
You can use this data to demonstrate Nonnormal Capability Analysis for Multiple Variables.
|Packaging Weight||The weight of each package|
|Machine||The machine identifier: Current or New|
