Nighthawk Airlines measured their numbers of lost bags in one month and found that they had lost 55 bags for 10,000 customers. If the average number of bags per customer is 1.3, how many errors per million opportunities (epmo) does this represent? The worldwide rate of baggage mishandling reported by SITA (Société Internationale de Télécommunications Aéronautiques) in 2013 was 6.96 per 1,000 passengers. If the average number of checked bags per passenger is assumed to be 1.3, how many errors per million opportunities (epmo) does this represent? How does this compare with the rate for Nighthawk-better or worse?
