A group of students conducted a science fair experiment to find out how the amount of fertilizer used will affect the growth of radish plants. The experiment was done using amounts of fertilizer that were less than and greater than the manufacturer’s recommendation. The table shows the average plant height in each test group after 10 days. Which inference is supported by the data?

• Giving radish plants too little or too much fertilizer will not affect plant growth.

• Giving radish plants too little or too much fertilizer will slow down plant growth.

• Giving radish plants more fertilizer will increase plant growth.

• Giving radish plants less fertilizer will increase plant growth.
