Dear Omar
Your t.test is telling that the 2 groups are not different. Now it is not clear
if you want to compute the CI for the difference or for each group. If the
former, then the outputs provides you with that information.
Itd be clearer if you provide the full syntax of your t.test. For example,
lets suppose I have 2 groups as vectors a and b, they are independent, they
have similar homogeneity, I want to use a two-tailed test, and I want a 95%CI
for the difference, so I type
t.test(a, b, alternative = c("two.sided"), paired = FALSE, var.equal = TRUE,
conf.level = 0.95)
Cheers,
Fer
