Wilcoxon Rank Sum test: Which one sided alternative hypothesis does SAS test, by default?

[Shristi]

Dear Members;

I have Pre and Post intervention data on 12 questions. I have calculated Median for all the 12 questions and applied the Wilcoxon test separately for all the questions. The compiled results are presented in a table. You can see that in question Q7 and Q8, P value (P<Z) is <0.0001. But I am not sure what alternative hypothesis is being tested in both the questions? 

Questions	Median
	Pre	Post	P<Z	P>|Z|
Q1	4	4	0.0761	0.1521
Q2	3	3	0.3202	0.6404
Q3	3	3	0.0176	0.0351
Q4	3	4	<.0001	<.0001
Q5	3	4	<.0001	<.0001
Q6	3	4	<.0001	<.0001
Q7	3	4	<.0001	<.0001
Q8	3	2	<.0001	<.0001
Q9	3	4	0.0013	0.0025
Q10	2.5	1	<.0001	<.0001
Q11	3	2.5	0.1027	0.2053
Q12	2.5	2	0.0403	0.0805

It would help to show the code used to generate the values as that is likely to contain the information you are requesting either by default (no specific alternative0 or an option.
