The following table shows the ranks given by two judges to the performance of six finalists in a men’s figure skating competition:
| Skater | A | B | C | D | E | F |
| Judge 1 | 3 | 5 | 1 | 6 | 2 | 4 |
| Judge 2 | 1 | 5 | 2 | 6 | 3 | 4 |
a. Specify the competing hypotheses to determine whether the Spearman rank correlation coefficient is different from zero.
-
H0: ρS = 0; HA: ρS ≠ 0
-
H0: ρS < 0; HA: ρS ≥ 0
-
H0: ρS > 0; HA: ρS ≤ 0
b-1. Calculate the Spearman rank correlation coefficient rS. (Round intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.)
b-2. Interpret the Spearman rank correlation coefficient rS.
-
Strong positive relationship.
-
Strong negative relationship.
-
Weak positive relationship.
-
Weak negative relationship.
c. The p-value for the test is found to be equal to 0.064. At the 5% significance level, does the Spearman rank correlation coefficient differ from zero?
-
No, since we do not reject H0.
-
Yes, since we reject H0.
-
No, since we reject H0.
-
Yes, since we do not reject H0.
