There are two types of machines,called type A and type B.Both type A and type B can be used to produce a certain product.The production manager wants to compare efficiency of the two machines.He assigns each of the 15 workers to both types of machines to compare their hourly production rate.In other words,each worker operates machine A and machine B for one hour each.These two samples are independent.
