Best Way to Compute/Approximate(?) Probabilty of a Point in a Given Distribution
...l distribution N[mean,stdev]. For example:
R> pnorm(0, 4, 10)
[1] 0.3446
means there is 34.46% chance of getting a value equal to or smaller
than 0 from a N(4, 10) distribution.
What I intend to get is: given the observed value "x", mean, and stdev
of normal distribution,
find the probabiltiy of "x" falls into that distribution.
Is there any reasonable way to obtain that?

strange fisher.test result
A simple question - using the following fishers test it appears that the P value is significant, but the CI includes 1. Is this result correct?
> data.50p10min <- matrix(c(16,15, 8, 24),nrow=2)
> fisher.test(data.50p10min)
Fisher's Exact Test for Count Data
data: data.50p10min
p-value = 0.03941

p-values
I apologize if this question is not completely
appropriate for this list.
I have been using SAS for a while and am now in the
process of learning some C and R as a part of my
graduate studies. All of the statistical packages I
have used generally yield p-values as a default output
to standard procedures.
This week I have been reading "Testing Precise
Hypotheses" by J.O. Berger
