Interpret the five-number summary and the box-and-whisker plot. Where does the middle portion of the data lie? The middle portion of the data are found to have an annual flow between a lower value of annual flows goes from a lower value of What is the interquartile range? to a higher value of and a higher value of The total spread of Can you find data outliers? (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.)

Use the coefficient of variation to make an estimate. (SALT may be helpful for performing part of this calculation.

Water and water rights have been fought over ever since ranchers and settlers moved into Wyoming, Montana, and the West. Even today farmers and ranchers fight cities and large developments over water from snowmelt that originates deep in the Rocky Mountains. A river starts in a massive and beautiful lake. Then it flows through prime trout fishing areas to a famous waterfall. After it leaves the park, the river is an important source of water for wildlife, ranchers, farmers, and cities downstream. How much water does leave the park each year?
