Another experiment on the spacing effect, this time on a watermelon tree, used five different levels of separation. The height of the trees in metres was measured after a certain amount of time, and the results are shown in the table below: 2.0 x 2.0m 2.8 x 2.8m 3.0 x 3.0m 3.5 x 3.5m 4.0 x 4.0m 7 12 14 19 7 7 17 18 25 10 15 12 18 22 11 11 18 19 19 15 9 18 19 23 11 i) Name the experimental design used in this experiment. ii) Complete a full analysis of variance at the 5% and 1% levels of significance. iii) On the treatments, perform a Duncan multiple range test at a 5% level of significance.
