5 2. Agribusiness researchers are interested in determining the conditions under which Christmas trees grow fastest. A random sample of equivalent-size seedlings is divided into four groups. The trees are all grown in the same field. One group is left to grow naturally (Group 1),one group is given extra water (Group 2), one group is given fertilizer spikes (Group 3), and one group is given fertilizer spikes and extra water (Group 4). At the end of one year, the seedlings are measured for growth(in height). These measurements are shown for each group. Group 1 Group 2 Group 3 Group 4 20 5 12 14 ERSIT 7 11 10 16 11 9 16 15 9 13 17 14 6 12 12 22 Determine whether there is a significant difference in the growth of trees in these groups. Use a = 0.01.
