Cakes baked by the Freshfood Bakery are transported from the ovens to be packaged by one of three wrappers. Each wrapper can wrap an average of 120 cakes per hour (Poisson distributed). The cakes are brought to the wrappers at the rate of 300 per hour (Poisson distributed). If a cake sits longer than five minutes before being wrapped, it will not be fresh enough to meet the bakery’s quality control standards. Does the bakery need to hire another wrapper?
