To determine how many standard deviations away from the mean an enrollment of 9000 is, you need to find the mean and standard deviation of the specific population or distribution in question. Once you have that information, you can use the formula:
where
is the number of standard deviations from the mean,
is the value in question (9000),
is the mean, and
is the standard deviation.
If you have those parameters (mean and standard deviation), plug them into the formula to calculate
and round it to two decimal places for your answer.
