Can a normal approximation be used for a sampling distribution of sample means from a population with μ=76 and σ=14, when n=49?
Solution :
Given that ,
mean = = 76
standard deviation = = 14
n = 49
sample distribution of sample mean is ,
=
= 76
sampling distribution of standard deviation
= / n = 14/ 49
= 2
