A consultant is helping a plant determine the best adhesive to stick a shiny strip on the floor to guide automated carts to their destination. There are two ways to lay the strip (paint or tape covered) and three types of floor coverings (linoleum, concrete I, or concrete 2) that can be used in facilities where carts are used. Identical tests are carried out for each type of ground cover and the band is placed using the two methods under study. Three random replicates are made and errors are counted every 1000 feet of the distance traveled by the cart. The data runs as scheduled. to. What is the goal of the problem? What is the experimental unit? What is the experimental design used? What is the response variable? What are the treatments? b. Write corresponding null and alternate hypotheses. c. For a 5% margin of error, what does the consultant conclude?
