estimating the population size
Line 22:
For example:
 
You take 4 random samples. The serial numbers are 2,7,34,13. Thus the difference is 34-2=32. The expected proportion is 0.6 The expected population size is 32 / 0.6 = 53 and the standard deviation of the expected proportion is 0.2
 
<pre>numofsamples = 2 proportion = 0.333 std_dev = 0.236
