Please let me ask you another quick question. I have results for e coli, and am trying to get 95% CI with the sd (1.783956). I got the result from another tool as (1.21, 3.42). But, I like to verify it with R. What function do you use for this?

> e.coli=c(27.5,24.6,25.3,28.7,23,26.8,24.7,24.3,24.9)
> sd(e.coli, na.rm = FALSE)

[1] 1.783956

Sorry for the newbie question.

thx much
