If this is the standard uniform U(0,1) distribution (which I assume from your phrase "*the* uniform distribution" (emphasis added)) then there will be no integers in the sample ... ?? > And I dont know what to do for B. > > 2nd Question > Simulate 1000 observations from the student-t distribution with 3 degrees of freedom and then calculate > the truncated mean by excluding bottom 5% and top 5%. Looks like homework questions, which are not answered on this list. Please read the posting guide; if these are *not* homework questions, please give us a plausible context. (Even if these are not homework questions, the posting guide asks that you "do your homework" in a broader sense by indicating what steps you have taken to solve your problem on your own before posting.) One hint for the second question: ?rt good luck, Ben Bolker ______________________________________________ R-help@r-project.org 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.
