Random samples of size n were selected from a nonnormal population with the means and variances given here. n = 13, μ = 129, o² = 1 What can be said about the sampling distribution of the sample mean? Since the sample size is ---Select--- 30, we ---Select--- 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.) mean standard error
