Exercise 20-41 Algo The accompanying data file shows the ranks given by two judges to the performance of six finalists in a men's figure skating competition. Click here for the Excel Data File a. Specify the competing hypotheses to determine whether the Spearman rank correlation coefficient is different from zero. Ho: Os = 0; HA: Os * 0 Ho: Os > 0; HA: Oss o O Ho: es < 0; HA: es 2 O b-1. Calculate the Spearman rank correlation coefficient rs. (Round final answer to 3 decimal places.) Rank correlation coefficient
b-2. Interpret the Spearman rank correlation coefficient rs. Strong positive relationship. Strong negative relationship. Weak positive relationship. O Weak negative relationship. c. The p-value for the test is found to be equal to 0.034. At the 10% significance level, does the Spearman rank correlation coefficient differ from zero? Yes, since we reject Ho. O No, since we do not reject Ho. Yes, since we do not reject Ho. O No, since we reject Ho.
