1) A student studied the effect of gibberellin (a plant hormone) on the growth of corn seedlings of the same height and species. A difference concentration of gibberellins in a fixed volume of water was applied to 7 groups of 10 plants each maintained under the same environmental conditions for the duration of the experiment. At the end of this period, the height of each plant was measured. The data are shown in the table below.
