           Wilcoxon rank sum test

data:  bfeed and marms
W = 158, p-value = 7.866e-12
alternative hypothesis: true mu is not equal to 0
95 percent confidence interval:
 -9.000012 -6.000045
sample estimates:
difference in location
             -7.999997

Warning messages:
1: cannot compute exact p-value with ties in:
wilcox.test.default(bfeed, marms, conf.int = TRUE, correct = FALSE) 2: cannot compute exact confidence intervals with ties in:
wilcox.test.default(bfeed, marms, conf.int = TRUE, correct = FALSE) >
