Wire electrical-discharge machining (WEDM) is a process used to manufacture conductive hard metal components. It uses a contin moving wire that serves as an electrode. Coating on the wire electrode allows for cooling of the wire electrode core and provides an improved cutting performance. An article gave the following sample observations on total coating layer thickness (in μm) of eight wi electrodes used for WEDM. 22 17 29 35 43 24 24 26 Calculate a 99% CI for the standard...
