I thought of another interesting scenario, and I would just go ahead and ask this. I have a mean (i.e. 26.2) where the number of e coli samples is 250. The mean is already calculated, so it is a discrete value, not series. What fucntion can be used for the calc with CI i.e. 90%? thx much, ej On

Thx so much, Chuck. R is a reallt sweet tool to use.. I can try many things with i.e. intervals (gls(e.coli ~ 1), level=0.90). It is a great help. ej On 10/19/06, Chuck Cleland <[EMAIL PROTECTED]> wrote: > Ethan Johnsons wrote: > > Please let me ask you another quick question. > > I have result

[R] CI with sd

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.
