I am new to R and Im some trouble with the following question... Generate 100
standard normal N(0,1) samples of size 100, X1(k),...,X100(k) where
k=1,...,100 (The k is and indicie in brackets) Calculate the sample mean for
each sample. For each sample mean Xbark the 0.95-confidence interval for the
mean mew=0 is given by... Ik= ( Xbark plus or minus 1.96/10) Find the number of
intervals such that 0 does not belong to Ik. How many of them do you expect to
see? Well so far I have come up with... N<-100; Nsamp<-100
A<-matrix(rnorm(N*Nsamp,0,1),ncol=Nsamp) means<-apply(A,2,mean) However I have
no idea what I am doing and no idea if that even makes sense. Any help would be
greatly appreciated as I have no experience of statistical software whatsoever.
Thanks in Advance. Rachel
