David, Thanks, its me getting mixed up I actually meant less than or equal to 10. That apart, I guess the code is OK, I just expected, especially as I increased N that I might have got some means less than 10, but having gone back to it , I see I need a million iterations before getting two means

try the following: LL <- c(12.5,17,12,11.5,9.5,15.5,16,14) n <- length(LL) N <- 1000 threshold <- 10 smpls <- sample(LL, N*n, replace = TRUE) dim(smpls) <- c(n, N) cnt <- sum(colMeans(smpls) > threshold) cnt I hope it helps. Best, Dimitris Graham Smith wrote: I am trying to modify some cod
