This utility calculates the expected probability of numbers of false positive results
to a test for a given sample size and test specificity, assuming the sample is from an uninfected population. It answers the question:
'For a given sample size and test specificity, and assuming that all animals are uninfected, what is the probability that there will be 1, 2, 3 etc false positives ?'.
It also answers the related questions: 'What is the probability of x (1, 2, 3, etc) or more false positive results? and
What is the probability of x (1, 2, 3, etc) or less false positive results?'
Inputs are the sample size tested and the test specificity.
Outputs are a table and graph of probabilities associated with each of the likely number of false positive results.
