18. Suppose the research hypothesis is supported using the hypothesis-testing procedure, but, in reality, the null hypothesis is true. What does this mean in the context of the study?
A. Increasing the amount of recess time does not improve in-class behavior , but the hypothesis test suggests that it does.
B. Increasing the amount of recess time improves in-class behavior , and the hypothesis test suggests that it does.
