Can a normal approximation be used for a sampling distribution
of sample means from a population with μ=78 and σ=14, when n=81?
why or why not?
Homework Answers
Yes, a normal approximation can be used for a sampling distribution of sample means from a population with μ=78 and σ=14, when n=81, because the sample size n=81 is adequate (n≥30) for using the normal approximation and the sampling distribution of the sample means also follows an approximate normal distribution even though parent population is skewed or non-normal and sample size is small.

When we sketch a sampling distribution of means, we often assume it will be normal in its shape, especially with a large enough sample size used for sampling means, even if the population distribution of scores we drew samples from is not normal in its shape. What allows us to make this assumption?
