Describe how you would apply the five basic steps of a statistical study to the given issue. You want to know the average volume of juice in your company's 500 mL bottles of orange juice.
What will be an ideal response?
Step 1: Population is all 500 mL bottles of orange juice made by your company; goal is to determine average volume of juice in those bottles.
Step 2: Choose a representative sample
Step 3: Determine average volume of juice for bottles in the sample.
Step 4: Infer average volume of juice for all 500 mL bottles of orange juice made by your company.
Step 5: Assess results and formulate conclusion

x? = 0.8x ? 0.4xy , y? = ?0.6y + 0.2xy
Let x and y represent the populations (in thousands) of two species that share a habitat. For each system of equations, find and assess the stability of the equilibrium points. Remember that, for real populations, both x0 and y0 must be nonnegative for ( x0, y0) to be an equilibrium point.
Solve the problem.A company packages its powdered iced tea mix in containers in the shape of a cylinder. The top and bottom are made of a plastic product that costs 5 cents per square centimeter. The side of the container is made of a cheaper material that costs 1 cent per square centimeter. The height of the cylinder can be found by dividing its volume by the area of its base. (i) If x is the radius of the base (in centimeters), write a rational expression in x whose values give the cost of each container, assuming that the capacity of the container is 70 cubic centimeters.(ii) Find the cost of a container whose base is 8 centimeters in diameter, using 3.14 as an approximation of ?. Round to the nearest cent, if necessary.
