Question: In Exercises 14.86-14.89, we repeat data from exercises in Section 14.2. For each exercise here,

  1. obtain the linear correlation coefficient by using the computing formula in Definition 14.6 on page 724.
  2. interpret the value of \(r\) in terms of the linear relationship between the two variables in question.
  3. discuss the graphical interpretation of the value of \(r\) and verify that it is consistent with the graph you obtained in the corresponding exercise in Section 14.2.
  4. square r and compare the result with the value of the coefficient of determination you obtained in the corresponding exercise in Section 14.3.
