Mann-Whitney Confidence Interval and Test

C2         N =  12     Median =      144.50
C1         N =  10     Median =      130.50
Point estimate for ETA1-ETA2 is       14.00
95.6 pct c.i. for ETA1-ETA2 is (10.00,18.00)
W = 185.5
Test of ETA1 = ETA2  vs.  ETA1 n.e. ETA2 is significant at 0.0019
The test is significant at 0.0019 (adjusted for ties)
