Case $3-$ Machine Shop

A Seattle machine shop produces slip$-$ring bearings resembling flat doughnuts or washers. They fit around shafts or rods, such as drive shafts in motors. At the early stage in the production process for a particular slip$-$ring bearing, the outside diameter of the bearing is measured. Employees have taken $10$ samples $($during $10$ days$)$ of $5$ slip$-$ring bearings$)$ and measured the diameter of the bearings. The individual observations from each sample are as follows:
