Most of our text reading regarding confidence intervals focuses on deriving and calculating their values under a variety of circumstances. More important than that, though, is what we can do with confidence intervals as engineers. Discuss how knowing the confidence interval for some statistical parameter (typically, but not always, the mean value) can affect the decision-making we conduct around that parameter on engineering projects. What might we do differently as a result of having confidence in a range of values rather than feeling we actually know a specific value?

In a study of the relationship between socio-economic class and unethical behavior, 129 university of california undergraduates at berkeley were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. they were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. after completing some unrelated tasks, participants reported the number of candies they had taken. it was found that those who were identiď¬ed as upper-class took more candy than others. in this study, identify: (a) the cases, (b) the variables and their types, (c) the main research question, (d) identify the population of interest and the sample in this study, and (e) comment on whether or not the results of the study can be generalized to the population, and if the ď¬ndings of the study can be used to establish causal relationships.
