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
