The Spearman rank-order correlation coefficient, rs, is the nonparametric version of r. It converts all (x, y) pairs to their corresponding (x rank, y rank) pairs and computes the correlation between the X and Y rankings. Below are 7 randomly generated (x, y) pairs: (14,35) (24,57) (29,85) (36,83) (53,39) (91,92) (94,29)

The Spearman rank-order correlation coefficient is found to be rs = -0.32

Which of the following 7 (x, y) pairs will also have rs= -0.32?

a. (8,31) (16,42) (20,46) (47,49) (56,58) (88,66) (97,91)
b. (8,65) (16,90) (20,41) (47,30) (56,45) (88,57) (97,48)
c. (8,6) (16,7) (20,2) (47,1) (56,3) (88,5) (97,4)
d. (1,66) (2,91) (3,42) (4,31) (5,46) (6,58) (7,49)
e. (8,1) (16,2) (20,3) (47,4) (56,5) (88,6) (97,7)
