The standard error of the mean is 12.

The standard error of the mean points to the standard deviation of the distribution of a sample mean obtained from a population.

The standard error S.E of the mean can be calculated by using the formula:

$\mathbf{S.E = \dfrac{\sigma }{\sqrt{n}}}$

where;

$\mathbf{S.E = \dfrac{24 }{\sqrt{4}}}$

$\mathbf{S.E = \dfrac{24 }{2}}$

S.E = 12
