Since the sample size is ---Select--- less than, equal to, greter than
---Select--- can, cannot assume that the distribution of x is approximately normal.

Random samples of size n were selected from a nonnormal population with the means and variances given here.
n = 90, µ = 39, o2 = 6
What can be said about the sampling distribution of the sample mean?
Since the sample size is --Select--- v 30, we --Select-- v assume that the distribution of x is approximately normal.
Find the mean and standard error for this distribution. (Round your standard error to four decimal places.)
