Question:
Given the following sampling distribution of a mean from a normally distributed population with a standard deviation of 12, find the sample size, n.

Standard Error:
In statistics, standard error indicated how much the sample mean is different from the population mean. The standard error (SE) of a statistic is the standard deviation of its sampling distribution or an estimate of that standard deviation. The standard error is given by the formula:
{eq}SE = \frac{\sigma}{\sqrt{n}} {/eq}
where,
{eq}\sigma {/eq} = standard deviation
{eq}n = {/eq} sample size
