Suppose the average math SAT score for students enrolled at local community college is 490.4 with a standard deviation of 63.7. A random sample of 49 students has been selected. The standard error of the mean for this sample is . 10.6 9.1 63.7 28.4 The standard deviation of X^bar (or the standard error of the sample mean) is calculated as the positive squareroot of the variance. It is computed as se(X^bar) = sigma/Squareroot n.
