    The standard error of the mean is labelled as: σM. The formula for the standard error is: where σ is the standard deviation of the original distribution and n is the sample size. The formula is σ / square root n

    So the given in our problem is:

    σ=36

    n = 81

    Standard Error = 36 / sqrt81

    = 36 / 9

    = 4
