Skills Developed:

Understand the application of average and range charts

Given:

Use the data shown in the table below. The specification for the bolt is $0\mathrm{.}745$ inches to $0\mathrm{.}755$ inches. You can use a zero value of $0\mathrm{.}750$ and all measurements shown in the table are added to this value. For example, a value of $5$ in the table is $0\mathrm{.}750+\mathrm{.}005$ equals $0\mathrm{.}755.$
