- Problem 21.2. An inspector reports a total of 16 defects out of a total batch size of 200 parts. On closer examination, it is determined that three of these reported defects were in fact good pieces, while a total of seven defective units were undetected by the inspector. What is the inspector’s accuracy in this instance? Specifically, what are the values of p1 and p2? (b) What was the true fraction defect rate?Nondestructive evaluation: Nondestructive evaluation (NDE) describes methodsthat quantitatively characterize materials, tissues, and structures by noninvasivemeans such as X-ray computed tomography, ultrasonics, and acoustic emission.Recently, NDE was used to detect defects in steel castings. (JOM, May 2005.)Assume that the probability that NDE detects a “hit” (i.e., predicts a defect in a steelcasting) when, in fact, a defect exists is .97. (This is often called the probability ofdetection.) Also assume that the probability that NDE detects a “hit” when, in fact,no defect exists is .005. (This is called the probability of a false call.) Past experiencehas shown that a defect occurs once in every 100 steel castings. If NDE detects a“hit” for a particular steel casting, what is the probability that an actual defectexists? Step by Step Full procedure required.A product line has two models: X and Y. Model X consists of 4 components: a, b, c, andd. The number of processing operations required to produce these four components are 2,3, 4, and 5, respectively. Model Y consists of 3 components: e, f, and g. The number of processingoperations required to produce these three components are, 6, 7, and 8 respectively.The annual quantity of Model X is 1,000 units and of Model Y is 1,500 units. Determine thetotal number of (a) components and (b) processing operations associated with these twomodels.
