Parachutes are woven in your factory using a synthetic fiber purchased from one of four different suppliers. Strength of these fibers is an important characteristic that ensures quality parachutes. You need to decide whether the synthetic fibers from each of your four suppliers result in parachutes of equal strength. Furthermore, your factory uses two types of looms to produce parachutes, the Jetta and the Turk. You need to establish that the parachutes woven on both types of looms are equally strong. You also want to know if any differences in the strength of the parachute that can be attributed to the four suppliers are .
