*Base your answers to questions 49-51 on the information and table below.
A farmer grows and sells flowering plants. The best-selling plants are the ones with the most blossoms.
The farmer buys new plant food that claims to make plants grow faster and taller. The farmer predicts that
taller plants will have more blossoms and performs the following experiment to test this hypothesis. Two
groups of 10 plants each are grown in identical pots filled with equal amounts of identical soil. The
amount of sunlight, the room temperature, and the amount of water are constant for both groups. Group A
is given plant food at regular intervals according to the instructions on the package. Group B is not given
plant food. The farmer observes the plants after 15 weeks of growth. The results are recorded below.
