ALFA ERROR, how do I calculate probability?

  1. Dec 18, 2011 #1
    Hello everybody,

    I have the following situation:

    A bulk drug has a purity specification of 98.5% to 101.0%. The precision for the bulk drug assay is σ = 0.92%.

    How do I calculate the the probability of obtaining a failing result for those cases where the sample is in fact 100% pure? By failing result I mean a result that falls out of specification.

    Thanks
