You work for a manufacturer of steel beams that will be used in construction of a heavily used bridge.  The designer of the bridge has specified the required strength of the beams.  Your job is to set-up a statistical analysis of the beam strength.  Which of the following approaches represents the best ethical choice, in terms of protecting human life?Group of answer choicesMeasure the strength of the first 10 beams manufactured, and if they are all meeting the specification, continue with the project.Measure the strengths from a random sample of the beams, and set-up a hypothesis test, with the null hypothesis that the beams meet the specifications. Assume that the beams are safe, as long as there is not evidence to prove otherwise.Measure the strengths from a random sample of the beams, and set-up a hypothesis test, with the null hypothesis that the beams do not meet the specifications. Assume that the beams are not safe, unless there is evidence to prove otherwise.

As a structural engineer, I enjoy designing the bridge in every detail, so I also focus on ensuring the quality of the materials used and the strength of the project's structure based on the materials used.

You work for a regulatory agency that oversees the certification of the safety of pesticides.  The manufacturer of a pesticide, used on tomatoes, claims that with proper use, the amount of the pesticide that will be in the tomatoes that go to market will be well below required standards.  Your job is to set-up a statistical analysis of the amount of the pesticide measured in tomatoes.  Which of the following approaches represents the best ethical choice, in terms of protecting human health?Group of answer choicesMeasure the pesticide level in a random sample of tomatoes, and set-up a hypothesis test, with the null hypothesis that the pesticide levels do not meet the standard. Assume that the pesticide is not safe, unless there is evidence to prove otherwise.Measure the pesticide level in tomatoes from one crate, and if they are all meeting the standard, certify the pesticide.Measure the pesticide level in a random sample of tomatoes, and set-up a hypothesis test, with the null hypothesis that the pesticide levels meet the standard. Assume that the pesticide is safe, as long as there is not evidence to prove otherwise.

Which of the following examples about ethical dimensions in engineering decision making is not acceptable?Group of answer choicesIn predicting alternative’s outcomes, use pessimistic estimates for one alternative, optimistic ones for othersIn constructing a model, use both long and short horizons to all alternativesIn assembling relevant data, clean and filter the data collectedIn identifying feasible alternatives, involve contractors that are new to the companyIn selecting criteria to determine the best alternative, emphasise safety while the financial situation is questionable
