 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)
