Six cities are selected, and the number of daily passenger trips (in thousands) for subways and commuter rail service is obtained. At α = 0.05, is there a relationship between the variables? Suggest one reason why the transportation authority might use the results of this study.

Perform these steps.
a. Find the Spearman rank correlation coefficient.
b. State the hypotheses.
c. Find the critical value. Use α = 0.05.
d. Make the decision.
e. Summarize the results.
Use the traditional method of hypothesis testing unless otherwise specified.
