The economic impact of an industry,such as sport fishing, can be measured by theretail sales it generates. In 2006, the economicimpact of great lakes fishing in states borderingthe great lakes had a mean of $318 and astandard deviation of $83.5. Note that all dollaramounts are in millions of dollars. Assume thedistribution of retail sales is unimodal andsymmetric. (Source: National Oceanic andAtmospheric Administration).If a new report came out saying that theeconomic impact of great lakes sport fishing onthe economy of Illinois was $93,588,546, wouldyou say this was unusual? Note that this dollaramount must be converted before calculating astandard score.Yes, it is unusually low.Not enough information availableNo, it is in the range of typical values.Yes, it is unusually high.
