I am trying to modify some code from Good 2005.
I am trying to resample the mean of 8 values and then count how many
times the resampled mean is greater than 10. But my count of means
above 10 is coming out as zero, which I know isn't correct.
If that is your goal, then why are you using "<=" and not ">" in your
test?

I would appreciate it if someone could look at the code below and tell
me what I am doing wrong.
Many thanks,
Graham
LL<- c(12.5,17,12,11.5,9.5,15.5,16,14)
N<-1000
n<-length(LL)
threshold<-10
cnt<-0
for(i in 1:N){
+ LLb <- sample (LL, n, replace=TRUE)
+ if (mean(LLb)<=threshold) cnt<-cnt+1
+ }
cnt
[1] 0
