Question 933455: Suppose a researcher is studying a population that has a mean of µ = 38.6 and a standard deviation of = 1.1. Round your answer to the nearest thousandth if needed.
The researcher studies a simple random sample of size n = 200. According to the central limit theorem, what is the approximate standard deviation of the sampling distribution of the mean?

You can put this solution on YOUR website!
SE = standard error = standard deviation of the sampling distribution

SE+=+sigma%2Fsqrt%28n%29

SE+=+1.1%2Fsqrt%28200%29

SE+=+0.07778174593052 Use a calculator here. This is approximate.

SE+=+0.078 Round to the nearest thousandth

The answer is approximately 0.078
