Sample Proportion
Let there be 
successes out of 
Bernoulli Trials. The sample proportion is the fraction of samples whichwere successes, so
 | (1) |
, 
has an approximately Normal Distribution.Let RE be the Relative Error and SE the Standard Error, then |  |  | (2) |
 |  |  | (3) |
 | |  | (4) |
where CI is the Confidence Interval and
is the Erf function. The number of tries needed to determine 
with Relative Error RE and Confidence Interval CI is | (5) |
