Assignment:
A physical-fitness researcher tests 25 professional football players, finding that the time required to run 40 yards (y, in seconds) is related to weight (x, in pounds) by the least-squares equation y^ = -2.0 + 0.038x According to this equation, a person weighing 200 pounds would run the 40-yard dash in an estimated time of 5.6 seconds. However, a child weighing 55 pounds would have an estimated time of just 0.09 seconds to run 40 yards. Briefly explain how this unlikely result could have been obtained.
Provide complete and step by step solution for the question and show calculations and use formulas.
