- (D) This study would most likely be done by comparing the average amount spent on organic food
between people who own hybird cars and people who don’t. This study could not be performed as
an experiment (there is no practical way to randomly assign people to “own hybrid cars” and
“don’t own hybrid cars” groups). The other research methods listed would not allow researchers
to conclude about the likelihood of spending money on organic food.
