Background Letter from Torrance Transit System to Dr. Drew.
Their Question If we only do two round-trips per survey day (362 round-trips, or 724 one-way trips), would our data meet the 95% confidence, 10% accuracy FTA criteria? If not, would there be a way of adding a few extra surveys to meet the standard?
