In this particular case the points lie on the top half of a circle. For the data in Exercise 12 of Section Example 1 Compute the linear correlation coefficient for the height and weight pairs plotted in Figure The answers to the second part of each question differ. Exercises The exercises in this section are unrelated to those in previous sections. 2. ### Zulugal
