9.
Which statement best expresses a basic scientific assumption?

11.
An experiment was carried out to determine whether drinking caffeinated soda increases pulse rate. The pulse rates of two groups of people at rest were measured. Group A was then given caffeinated soda and group B was given caffeine-free soda. One hour after drinking the soda, the pulse rates were measured. The participants in the experiment were all the same age, and they were all given the same amount of soda. The dependent variable in this experiment is the
a)
type of soda given to each group
b)
amount of soda given to each group
c)
pulse rate of each group
d)
age of participants in each group
