deviation of 28. Random samples of size n = 64 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 =_______.
