Question 287676: suspose that the population standard deviation (ơ) for a mormally distributed standardized test of achievement is known to be 7.20. What would the standard error of the sample mean be if we were to draw a random sample of 16 test scores?

suspose that the population standard deviation (ơ) for a normally distributed standardized test of achievement is known to be 7.20. What would the standard error of the sample mean be if we were to draw a random sample of 16 test scores?
------------------
standard error = t(7.20/sqrt(16))

Note: You have to know the level of confidence to get the
appropriate t-score.
