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? The annual flow of the river (units 10 cubic meters) is shown here for 19 recent years. 25.9 32.4 33.1 19.1 17.5 24.9 21.0 45.1 30.8 34.3 27.1 29.1 25.6 31.8 23.1 24.1 23.9 25.9 18.6 LA USE SALT (a) Is there a "guaranteed" amount of water farmers, ranchers, and cities will get from the river each year? Yes, flows average out to the same value across each year. No, annual flows change at a steady rate from year to year. No, annual flows are a random variable. Yes, flows occur at the same rate at corresponding times throughout the year. Yes, flows occur at a constant rate. (b) What is the. "expected" annual flow from the snowmelt? Find the mean, median, and mode. (Round your answers to two decimal places.) mean X median Enter a number. mode (c) Find the range and standard deviation of annual flow.
