Since the sample size is ---Select--- less than, equal to, greter than  30, we
---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.

\[
n = 13, \mu = 130, \sigma^2 = 1
\]

What can be said about the sampling distribution of the sample mean?

Since the sample size is ---Select--- \( \geq \, 30 \), we ---Select--- assume that the distribution of \( \bar{x} \) is approximately normal.

Find the mean and standard error for this distribution. (Round your standard error to four decimal places.)
