In an effort to check the quality of their cell phones, a manufacturing manager decides to take a random sample of 10 cell phones from yesterday’s production run, which produced cell phones with serial numbers ranging (according to when they were produced) from 43005000 to 43005999. If each of the 1000 phones is equally likely to be selected: What distribution would they use to model the selection? What is the probability that a randomly selected cell phone will be one...

Many companies use a quality control technique called acceptance sampling to monitor incoming shipments of parts raw materials and so on. In the electronics industry, component parts are commonly shipped from suppliers in large lots. Inspection of a sample n components can be viewed as the n trials of a binomial the experiment. That outcome for each component test (trail) will be that the component is classified as good or defective. Reynolds Electronics accepts a lot from a particular supplier...
