ou are working with a company on the monitoring of the operation of a router in the manufacture of a biomedical plastic product. Both a leading$-$edge and a trailing$-$edge measurement were made on each piece. The design for the piece speci$$ed that both leading$-$edge and trailing$-$edge values were to have a target value of $0\mathrm{.}172$ cm$.$

In this situation, the correspondence between leading$-$ and trailing$-$edge di$-$

mensions is critical to proper $$t in a later assembly operation. The within piece pairing argues for you to use a paired statistical test to analyze if the correspondence between the edges is equal.
