CMS Curriculum Guide 2011-2012 Advanced Functions & Modeling Unit Title: Statistics and Probability suggested time: 17 days Enduring understanding (Big Idea): Statistics are extremely important in engineering. In environmental engineering, hypothesis testing can be used to determine if a change of an emission level for a chemical as a significant impact on overall pollution. Also, confidence intervals can be used to help suggest restrictions on by-product wastes in ground water. Essential Questions: How are statistics used for decision making in business and science? What are the limitations of statistics?
