2. A plant biologist wants to test the effectiveness of a plant hormone on a certain plant species. She uses 3 seeds from the same plant to start her experiment. The seeds are planted at the same depth of soil and given the same amount of water and sunlight. She applies 10 mg of hormone to the first plant, 5 mg to the second plant and no plant hormone to the third plant. After 30 days she finds that the plant with the 5 mg of hormone grew the fastest and the tallest. She then repeats her experiment 2 more times.

Did this experiment give accurate results? Why or why not?
