What steps do I take to calculate “Suppose x has a distribution with a mean of 40 and a standard deviation of 28. Random samples of size n = are drawn. (the – next to the x indicates that the – is over the x in the question) Describe the -x distribution and compute the mean and standard deviation of the distribution.

-x has ____ distribution with mean μ-x = ____ and standard deviation σ-x =_______.
