Question:
=15-21 V. S. Industries in Parkersburg, West Virginia is a small manufacturer of military grade hybrid microcircuits. One of the many quality assurance procedures required by Military Standard 883J
(MIL-STD-883J) for hybrid microcircuits is known as nondestructive bond pull (method number 2023.7 in MIL-STD-883J). The procedure involves pulling on a random sample of wires within the hybrid microcircuit with a prespecified amount of force. If the wire tears, breaks, or separates in any way from the circuit it fails the test and is considered defective and scrapped. In a recent batch of 1000 devices 13 failed the pull test. Determine upper and lower control limits for the associated p-chart.
