In a biological experiment, 4 chemical concentrations are used to enhance the growth of a certain type of plant over a specific period of time. The following growth data, measured in centimeters, were recorded for the plants: Concentration 2 3 Observations 4 8.2 7.7 6.9 6.8 8.7 8.4 5.8 7.3 3 9.4 8.6 7.2 6.3 4 9.2 8.1 6.8 6.9 Total 35.5 32.8 26.7 27.3 Mean 8.875 8.200 6.675 6.825 At the level of significance 5%, test the hypothesis that there is no difference in the average growth of these plants for the different concentrations of the chemical?
