What is the interquartile range? Can you find data outliers? (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) (f) Another river is a smaller but very important source of water flowing out of the park from a different drainage. Ten recent years of annual water flow data are shown below (units 108 cubic meters). 3.83 3.81 4.01 4.84 5.81 5.50 4.31 5.81 4.31 4.37 Although smaller, is the new river more reliable? Use the coefficient of variation to make an estimate. (Round your answers to two decimal place.) original river's coefficient of variation smaller river's coefficient of variation What do you conclude? Neither river is more consistent. The original river is more consistent. The smaller river is more consistent. (g) Based on the data, would it be safe to allocate at least 27 units of the orginal river water each year for agricultural and domestic use? Why or why not? No, the median is less than 27 which means more than half the river flows are below 27. No, Q3 is less than 27 which means more than three quarters of the river flows are below 27. No, since 27 is an upper outlier it will be very rare to have a flow at or above 27. Yes, Q1 is greater than 27 which means over three quarters of the river flows are at or above 27. Yes, since 27 is an lower outlier it will be very rare to have a flow below 27.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
In the Western United States there is a saying, "Whisky is for drinken but water is for fighten!" 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? The annual flow of the river (units 108 cubic meters) is shown here for 19 recent years.
