In a biological experiment, 4 concentrations of a certain chemical are used to enhance the growth of a certain type of plant over a specified period of time. The following growth data, in centimeters, were recorded for the plants that survived: Use a 0.01 level of significance. Test the hypothesis if there is a significant difference in the average growth of these plants for the different concentrations of the chemical. What is the statistical decision?

• Reject the null hypothesis.

• Accept the null hypothesis.
