Line 175:

To do so, calculate the difference between the largest serial number and the smallest serial number in your sample. The expected population size of the item is that difference divided by the expected proportion.

'''Example'''

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

Line 194:

numofsamples = 15 proportion = 0.875 std_dev = 0.080
