## Creating a Histogram: CNC Vendor Facility Example

The following data are from a runoff held at the CNC vendor's facility. The indicated portion of the shaft was chosen for inspection. The diameter specifications for the round shaft are 7.650 + 0.02 mm. In order to prevent scrap for this particular operation, there is no lower specification. The data are scaled from 7.650, that is a value of 0.021 is actually 7.671mm.

Create a histogram with the data.
