Explanation:

Chandra predicted soda - fed plants would grow more. But water - fed plants grew 8.3 cm (average) and soda - fed grew 5.6 cm. Since 5.6 < 8.3, the data shows soda - fed plants grew less, so it rejects her prediction.

Answer:

Her data rejects her prediction. Because the average growth of water - fed plants (8.3 cm) is greater than that of soda - fed plants (5.6 cm), meaning soda - fed plants did not grow more as she predicted.
