Let the random number generator which produces only 1's ad 2's (I,e, X=1,2 for all N)
Determine mean,u, and variance o squared x of the distribution?
For sample size 3, ie n=3, find all possible sampling outcomes for average value X bar.
Create sampling distribution of X bar for n=3 Xbar P(Xbar)
Find mean and standard deviation of sampling distribution for n=3?
