As a quality control manager at Tinker Air Force Base, you perform inspections on shipments of components from suppliers to detect nonconforming components. Assume a lot contains 1000 components and 1% are nonconforming. What sample size is needed so that the probability of choosing at least one nonconforming component in the sample is at least 0.90? Assume a binomial distribution (that is, assume that 1000 is sufficiently large so that we can assume replacement). Solve analytically.
