Energy is measured in kilowatt hours. The table below shows the cost of building
a facility to produce energy and the ongoing cost of operating the facility for
five different types of energy.

Construct a scatter plot of the cost to build the facility (x) and the cost to operate the facility (y). Use the grid below, and be sure to add an appropriate scale to the axes.

Do you think that there is a statistical relationship between building cost and operating cost? If so, describe the nature of the relationship.

Based on the scatter plot, can you conclude that decreased building cost is the cause of increased operating cost? Explain.
