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?

Solutions

Expert Solution

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
