1. Many companies use a 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 of n components can be viewed as the n trials of a binomial experimem. The outcome for each component tested (trialD will be that the component is classified as good or defective defective components in the lot do not exceed 1 %. Suppose a random sample of fiver...

Case 2: Going to The X-Stream Gil Reihana is the chief executive officer of X-Stream, an Auckland-based company that assembles personal computers for the New Zealand and Australian markets, and sells them through a number of chain stores and independent retailers. He started the company six years ago, at the age of 25, after graduating from university with a Bachelor’s degree in Information Technology and Management. To establish the company, Reihana invested $300 000 he had inherited and persuaded various...
