An analyst gathers the following information about a sample:

Mean: 12
Number of observations: 50
Variance: 32

The standard error of the sample mean is closest to ______.

Explanation: The standard error of the sample mean is the sample standard deviation (or the population standard deviation if known) divided by the square root of the sample size. In this case, the standard error of the sample mean = 32^0.5 / 50^0.5 = 0.80.
