ABSTRACT
This chapter presents examples to highlight the use of quantitative methods in environmental health and safety projects. The main intention of the solutions is to present all the basic steps for use with a calculator and identify the applicable equations. The marketing manager presented a strong case against purchasing the new equipment. However, the safety manager used decision tree and expected values to support the hypothesis that the project is profitable. The safety manager used his knowledge of sampling and estimation to show that the sampling sizes of 100 per batch were insufficient to establish with 95% confidence level that less than 25% of the components are defective. The null hypothesis can be translated to read that opinion in all groups is spread in these proportions. The safety manager collected data and did a linear programming exercise to show that the same profit or more can result from producing less of product.
