I have just completed a payment time cycle analysis for my companys process realting to our collecting of timecards/inputing/invoicing/collection of funds & dispearsment of funds to vendors.The total number of timecards processed for time frame we are reviewing is approx. 250,000, we sampled 800 timecards reviewing 5 different data points(dates). My question is how can I assign a level of confidence regarding this work?
