Commercial fi sh farming is a growing industry in Europe. What makes fi sh raised commercially grow faster and larger? Suppose that a fi sh industry study is conducted over the three summer months in an eff ort to determine whether the amount of water allotted per fi sh makes any diff erence in the speed with which the fi sh grow. Th e data below represent the inches of growth of salmon in fi sh farms for diff erent volumes of water per fi sh. Use  0.01 to test whether there is a signifi cant difference in fi sh growth by volume of allotted water. 1 Litre per Fish 5 Litres per Fish 10 Litres per Fish 1.1 2.9 3.1 1.4 2.5 2.4 1.7 2.6 3.0 1.3 2.2 2.3 1.9 2.1 2.9 1.4 2.0 1.9 2.1 2.7
