public ConfidenceInterval(double lowerBound,
                          double upperBound,
                          double confidenceLevel)
```
    Create a confidence interval with the given bounds and confidence level.
    Preconditions:
    
    lower must be strictly less than upper
    
    confidenceLevel must be strictly between 0 and 1 (exclusive)
    Parameters:
    
    lowerBound - lower endpoint of the interval
    
    upperBound - upper endpoint of the interval
    
    confidenceLevel - coverage probability
    
    Throws:
    
    MathIllegalArgumentException - if the preconditions are not met
