### A population that consists of 500 observations has a mean of 40 and a standard deviation of 15 A sample of size 100 is taken at random from this population The standard error of the sample mean equa?

The formula for calculating the standard error (or some call it
the standard deviation) is almost the same as for the population;
except the denominator in the equation is n-1, not N (n = number in
your sample, N = number in population). See the formulas in the
related link.

### What is the significance of standard error of estimates?

Standard error is an indicator of the expected level of
variation from the predicted outcome in an estimate. So even though
the mean is mostly likely the outcome, the actual range the outcome
could call into is a region which is measured by the standard
error.

### Is standard deviation same as standard error?

From what ive gathered standard error is how relative to the
population some data is, such as how relative an answer is to men
or to women. The lower the standard error the more meaningful to
the population the data is.
Standard deviation is how different sets of data vary between
each other, sort of like the mean.
