Question: A government economist obtained the following data from a simple random sample of ten private companies in the natural gas exploration business. In the table below, x is the capital investment the company puts into exploration and development (in millions of dollars) and y is the volume of natural gas discovered (adjusted to sea level pressure and in billions of cubic feet).

x	5.8	8.3	1.7	7.7	5.6	2.4	15.8	10.1	12.4	7.9
y	9.1	17.4	4.7	12.3	3.8	4.6	18.1	19.3	16.9	12.6

Draw the scatter diagram for this data.
Find the slope, b, and the intercept, a, for the least-squares line. Write the equation of the least-squares line.
Graph the least-squares line on your scatter diagram.
If a company had invested 6.5 million dollars, what would the least-squares line predict for the volume of natural gas discovered?
