Support beam thickness data

A production engineer wants to investigate the capability of the process that manufactures support beams. The engineer thinks that the process capability might differ between the morning and evening shift. The engineer measures the thickness of five samples out of 10 boxes from each shift. The thickness must be between 10.44 mm and 10.96 mm to meet the customer requirements.

You can use his data to demonstrate Normal Capability Analysis for Multiple Variables.

Worksheet column Description
Shift The shift in which the support beam was manufactured: 1 or 2
Thickness The thickness of each support beam
