What is the appropriate order of the stages of investigating whether maple trees drop their leaves in the autumn because of colder days? (1) Maple trees are grown in 2 greenhouses where the only variable is temperature (15°C vs. 10°C). (2) The hypothesis is rejected. (3) There is no statistical difference in the number of leaves dropped at 10°C as compared to 15°C. (4) The observation is that maple trees drop their leaves in autumn. (5) The hypothesis is that maple trees drop their leaves because of colder temperatures.

What is a valid, testable prediction based on this hypothesis?
