      public ConfidenceInterval createInterval​(int numberOfTrials, int numberOfSuccesses, double confidenceLevel)
      Create a confidence interval for the true probability of success of an unknown binomial distribution with the given observed number of trials, successes and confidence level.

      Preconditions:

      • numberOfTrials must be positive
      • numberOfSuccesses may not exceed numberOfTrials
      • confidenceLevel must be strictly between 0 and 1 (exclusive)
      Specified by:
      createInterval in interface BinomialConfidenceInterval
      Parameters:
      numberOfTrials - number of trials
      numberOfSuccesses - number of successes
      confidenceLevel - desired probability that the true probability of success falls within the returned interval
      Returns:
      Confidence interval containing the probability of success with probability confidenceLevel
