Open the Galileo.xls workbook and go to the Q&A sheet. This data set was con- structed with a different gravitational constant. It appears our fictional Galileo has traveled to another, bigger planet. Use the data set to answer the following questions:
a. Run regressions for the linear and quadratic models. Report your results in the standard Predicted Y = b + mX format.
b. Is the quadratic model still better? Explain why.
c. For the quadratic model, compute the derivative of Predicted Distance with respect to Time.
