4. To test a new medicine, each of 300 volunteers was
assigned a distinct number from 1 to 300. Next, a
calculator was used to simulate drawing 150 balls from

to receive the new medication would be chosen without
bias. The other volunteers received a placebo. Weeks
later, the 2 groups were compared. Which of the
following phrases best describes the company's testing?
F. Rondomized census
G. Randomized experiment
