Question

Perform rank correlation analysis on the following data set:

x	y
-3	-40
-2.55	-38
-2.05	-21
-1.55	-29
-1.1	3
-0.65	6
-0.35	-14
-0.05	2
0.5	21
0.8	-17
1.25	4
1.75	-3
2.15	19
2.45	4
3.05	10
3.45	52
4.05	55
4.45	84
4.75	77

What is the rank correlation coefficient?  (Round to three decimal places.)

What is the critical rho value at a 0.05 significance?

Do we have correlation?

• Yes, the rank correlation coefficient is smaller (in absolute value) than the critical rho value.
• No, the rank correlation coefficient is larger (in absolute value) than the critical rho value.
• Yes, the rank correlation coefficient is larger (in absolute value) than the critical rho value.
• No, the rank correlation coefficient is smaller (in absolute value) than the critical rho value.
