(solution) Consider the following discrete population distribution: X 2 4 6

(solution) Consider the following discrete population distribution: X 2 4 6

Consider the following discrete population distribution:

X 2 4 6 8
P(X = x) 0.13 0.34 0.23 0.30

We randomly draw samples of size 5 from this population using the simple random sampling technique. If we know that ?x = 5.4, ?x = 2.069, what is the mean and standard deviation of the sampling distribution of sample means?
