The standard error of the mean is the standard deviation of the sampling distribution of the mean. It is calculated by dividing the population standard deviation by the square root of the sample size. In this case, the population standard deviation is 12 and the sample size is 36, so the standard error of the mean is 12 / sqrt(36) = 2.
