A population has parameters μ=126.3μ=126.3 and σ=57.9σ=57.9. You
intend to draw a random sample of size n=221n=221.
What is the mean of the distribution of sample means?
What is the standard deviation of the distribution of sample means?
(Report answer accurate to 2 decimal places.)
Given that ,
mean = = 126.3
standard deviation = = 57.9
n = 221
sample distribution of sample mean is ,
sampling distribution of standard deviation
= / n = 57.9 / 221=3.8948
