hi all I have a question about drawing the confidence interval .
For instance,if I want to sample 100 times,and each time,the sample
size is 10,and the mean and sd is 15 and 1 respectively .I want to draw
the 100 confidence intervals(as the attachment) .Which function should
be used to draw the confidence interval ?
This list does not answer questions about homework.
(BTW, no attachment came through; only a *very* limited range of file
types is permitted for attachments).
cheers,

As was pointed out your attachment didn't make it to the list, so we
don't know what you want plotted, and your problem statement wasn't
clear (at least to me).
Usually, it you want help on this list, you should provide a
reproducible example. In your case, at least show us what you tried.
If you provide code to generate your random samples, and then describe
what you want, e.g. "plot sample means and standard errors estimated
from the samples," we can play along at home. Then you may get some
usable help.
You could also Google something like "R plot means and standard errors".
