Two case studies are used to illustrate the wide range of practical problems for which statistical computation is required.
Case 1: Is it a Baby or a Bathtub?i
Safety related complaints have been received about a newly marketed product. Should the product be recalled? Methodology for answering this question will be discussed.
Case 2: How Much Fish is Consumed by Anglers on the Passaic River?
A multiday survey of anglers on the Passaic River has been conducted. We are asked to estimate the amount of fish consumed by the anglers. Statisical methods for estimating the number of anglers and the amount of fish consumed are presented. Computational methods for dealing with sparce information are discussed.
