Suppose that you take a sample of size 50 from a population that is not normally
distributed. Can the sampling distribu
ti
on of
x
be approximated by a normal
probability distribu
ti
on?
Yes, the sample size can be approximated by a normal probablity ditribution
because the sample size is greater than 30.

Yes. The sample size is greater than 30, therefore, we may
approximate by a normal probability distribution.
