Exercise 20-40 Algo Consider the following competing hypotheses and accompanying sample data. Use Table 1. HO: Osso HA: Os > 0 rs = 0.39 and n= 35 a-1. Calculate the value of the test statistic. Assume the normal approximation for rs. (Round final answer to 2 decimal places.) Test statistic

a-2. Find the p-value. 0.01 Picture p-value < 0.025 O p-value < 0.01 O p-value Picture 0.10 0.05 Picture p-value < 0.10 0.025 Picture p-value < 0.05 < b. At the 1% significance level, what is the conclusion? Do not reject Ho; since the p-value is less than the significance level. Do not reject Ho; since the p-value is greater than the significance level. Reject Ho; since the p-value is less than the significance level. O Reject Ho; since the p-value is greater than the significance level.

c. Interpret the results. We cannot conclude that the Spearman rank correlation coefficient differs from zero. We conclude that the Spearman rank correlation coefficient differs from zero. We cannot conclude that the Spearman rank correlation coefficient is less than than zero. We conclude that the Spearman rank correlation coefficient is less than than zero.
