Consider the following sample of production volumes and total cost data for a manufacturing operation.

Production Volume (units)	Total Cost ($)
400	4000
450	5000
550	5400
600	5800
700	6300
750	7000

This data was used to develop an estimated regression equation, ? = 1,305.33 + 7.44x, relating production volume and cost for a particular manufacturing operation. Use ? = 0.05 to test whether the production volume is significantly related to the total cost. (Use the F test.)

State the null and alternative hypotheses:
