Question: a. Convert the data in part (a) of Exercise 3 to ranks, separately for each variable, in order to compute the Spearman rank-order correlation coefficient.

a. Convert the data in part (a) of Exercise 3 to ranks, separately for each variable, in order to compute the Spearman rank-order correlation coefficient. Test r_S for statistical significance by using Table I. Compare r_S to the Pearson r that you calculated for Exercise 3, part (a).

b. Redo part (a) for the data in part (c) of Exercise 3 (i.e., with X rearranged).
