The impact of dropping hollow balls was investigated in the American Journal of Physics (Mar. 2014). Standard
Question:
a. Conduct a complete simple linear regression analysis of the relationship between coefficient of restitution (y) and impact speed (x). Write all your conclusions in the words of the problem.
b. The researcher believes that the rate of increase in the coefficient of restitution with impact speed differs depending on whether the ping-pong ball buckles. Do the data support this hypothesis? Explain.
