I have a quick question, please. Does R have function to compute i.e. a 90% confidence interval for the mean for these numbers?
> mean (6,11,5,14,30,11,17,3,9,3,8,8) [1] 6 I thought pt or qt would give me the interval, but it seems not. thx much. ej ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
