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 ?

Many thanks!
