    Graduate Confidence Intervals for not integers numbers ratio

    Ok, I'm calculating an efficiency to pass a selection of some data. In this data there is some background that I want to subtract. In order to do so I have a simulated sample of the background. This simualted sample is scaled with several weights. (normalization, efficiency correction, etc..)...

This kind of intervals are usually defined for ratios between integers numbers but in my case I had to subtract from both numerators and...
